Responsible alcohol service

Alcohol is part of what Juniper Street sells, and the bar brings in a good share of the restaurant's revenue. It is also the single biggest factor behind the incidents in the last two lessons, behind many slips and falls in the dining room, and behind the most serious harm a restaurant can contribute to: an intoxicated guest who leaves and drives. Serving alcohol responsibly protects the guests, the public, the staff and the business. This lesson covers the training and permits servers need, how alcohol affects the body, how to check age, how to pace service and how to recognize intoxication. The next lesson covers refusing service and the legal consequences of over-service.

Training and permits

In Georgia, alcohol service is licensed by the state Department of Revenue and by the city or county. State law does not require server training everywhere, but many local governments do. The City of Savannah requires anyone who serves alcohol to hold a Server Training Permit Card, which is issued free and valid for five years after the city's training. Juniper also has every server and bartender complete a nationally recognized responsible alcohol service course, which some insurers reward with lower premiums and which can help show reasonable care if the restaurant is ever sued. Olivia keeps copies of every permit and certificate in the staff file. The legal drinking age is 21.

Training is the minimum. What makes service responsible is a house policy that everyone follows, a manager who backs staff up, and a bar and dining room set up to make good choices easy: food available until the bar closes, non-alcoholic drinks that are as appealing as the cocktails, water on every table, and no promotions that push guests to drink quickly.

What a standard drink is

Guests and staff talk about "a drink", but a pint of strong craft beer, a generous pour of wine and a double martini contain very different amounts of alcohol. Health agencies use the idea of a standard drink, a fixed amount of pure alcohol, to compare them.

In the United States, a standard drink contains 0.6 oz (14 g) of pure alcohol. That is a 12 fl oz (355 mL) can of 5% beer, a 5 fl oz (148 mL) glass of 12% wine, or a 1.5 fl oz (44 mL) shot of 40% spirits.

Many popular drinks are more than one standard drink. A 16 oz (473 mL) pint of 7% IPA is about two. A cocktail with two shots of spirits is two. A large glass of 14% wine poured to 8.5 oz (250 mL) is about two. Servers who count glasses rather than standard drinks will underestimate how much a guest has had.

How alcohol affects the body

Alcohol is absorbed into the blood through the stomach and small intestine, mostly the small intestine. Food in the stomach slows absorption, which is why guests who eat drink more safely than guests who drink on an empty stomach. Once in the blood, alcohol reaches the brain within minutes. The liver breaks it down at a roughly fixed rate, on average about one standard drink an hour, and nothing speeds that up: not coffee, not cold showers, not fresh air. Only time lowers blood alcohol.

Blood alcohol concentration (BAC) depends on how much alcohol a person drinks, how fast, their body size and composition, whether they have eaten, and other factors such as medications, fatigue and illness. For the same number of drinks, a smaller person, a person who has not eaten, or a person who drinks quickly will reach a higher BAC. On average, women reach a higher BAC than men of the same weight, because of differences in body water.

As BAC rises, the effects follow a familiar order. Inhibitions drop first: people get louder, more talkative and more confident. Judgment goes next: they make poor decisions, such as ordering another round or deciding to drive. Then reaction time slows, and finally coordination fails: slurred speech, stumbling, spilled drinks. Servers are trained to notice the early changes, in inhibitions and judgment, because by the time coordination fails, the guest has usually had too much.

For driving, Georgia law sets the limit at a BAC of 0.08 for most drivers, 0.04 for commercial drivers and 0.02 for drivers under 21. Impairment can be charged at any level if alcohol affects safe driving.

Estimating, carefully

Bartenders sometimes ask how many drinks it takes to reach a given BAC. The honest answer is that it varies too much between people to count on. The Widmark formula, used by toxicologists, gives a rough estimate from the amount of alcohol, body weight, a body water factor and the time since drinking began. Juniper uses it only in training, to show how quickly a guest can reach the legal driving limit, never to decide whether a particular guest is safe to drive.

# Rough blood alcohol estimate (Widmark formula). Training use only: people vary widely.
GRAMS_PER_DRINK = 14.0       # US standard drink
ELIMINATION = 0.015          # BAC units per hour, a typical average
LB_TO_KG = 0.4536

def bac(drinks, body_lb, hours, r):
    grams = drinks * GRAMS_PER_DRINK
    peak = grams / (body_lb * LB_TO_KG * 1000 * r) * 100
    return max(0.0, peak - ELIMINATION * hours)

for label, lb, r in [("guest A, 200 lb, r=0.68", 200, 0.68), ("guest B, 130 lb, r=0.55", 130, 0.55)]:
    print(label)
    for drinks in (2, 3, 4, 5):
        print(f"  {drinks} drinks over 2 h: about {bac(drinks, lb, 2, r):.3f}")

guest A, 200 lb, r=0.68
  2 drinks over 2 h: about 0.015
  3 drinks over 2 h: about 0.038
  4 drinks over 2 h: about 0.061
  5 drinks over 2 h: about 0.083
guest B, 130 lb, r=0.55
  2 drinks over 2 h: about 0.056
  3 drinks over 2 h: about 0.100
  4 drinks over 2 h: about 0.143
  5 drinks over 2 h: about 0.186

On these assumptions, the lighter guest passes 0.08 after three drinks in two hours, and the heavier guest reaches it at about five. Even these rough numbers make the point for new servers: a guest can be over the driving limit long before looking drunk. That is why a server's job is to watch the pace and the early signs, and why Juniper never tells a guest that they are safe to drive.

Checking age

Serving a minor is one of the most serious violations in alcohol law, for the license holder and for the server, and in Georgia it can be a criminal charge as well as a reason for the city to suspend the license. Juniper's rule is to ask for ID from anyone who looks under 30. Acceptable ID is a valid, government-issued photo ID with a date of birth, such as a driver's license, a state ID card, a passport or a military ID. Staff check that the photo matches, that the ID is not expired, and that the date of birth makes the guest 21 or older; a vertical-format Georgia license means the holder was under 21 when it was issued. If there is any doubt, the server refuses service, and the manager backs that decision.

Checking ID is also a common trigger for arguments, especially with groups. Servers ask politely and consistently, explain that it is the law and the house policy, and never make exceptions for regulars, friends or people who seem offended. Refusing to serve a guest who cannot prove their age is always the right call.

Pacing and preventing intoxication

The easiest guest to deal with is one who never becomes intoxicated in the first place. Juniper's servers and bartenders use a few simple habits that slow the pace without lecturing anyone:

• Offer food with drinks, especially to guests who are drinking before or instead of eating.
• Bring water to every table and refill it without being asked.
• Serve one drink at a time per guest; no doubles of the same drink lined up, and no shots for large groups without the manager's approval.
• Count standard drinks, not glasses, and keep track of what each guest at the bar has had.
• Slow down service to a guest who is drinking quickly: clear the empty glass first, check in before offering another round, and suggest a non-alcoholic option.
• Pass information along at shift change, so the next bartender knows who has had several drinks.

Recognizing intoxication

There is no single sign that proves a person is intoxicated, but several signs together are a strong indication. Servers watch for changes from how the guest was when they arrived.

• Lowered inhibitions: louder, overly friendly, telling inappropriate jokes, using bad language.
• Impaired judgment: ordering more and faster, buying rounds for strangers, arguing, complaining about drink strength.
• Slowed reactions: slow responses, losing track of the conversation, forgetting what they ordered.
• Loss of coordination: slurred speech, stumbling, swaying, dropping money or keys, spilling drinks, difficulty picking up change.

When a server notices early signs, the right move is to slow service and tell the bartender and the manager, not to wait until the guest is visibly drunk.

Non-alcoholic drinks

A well-made non-alcoholic option is one of the easiest ways to help guests pace themselves, and it gives designated drivers and guests who have had enough something better than a soda. Juniper's bar keeps three alcohol-free cocktails on the menu, made with the same care and glassware as the others, plus non-alcoholic beer. Servers offer them without making a point of it, especially when a guest slows down or says they are driving. Nadia's rule is that nobody should ever feel singled out for ordering one.

Medications, fatigue and other factors

Alcohol does not act alone. Many common medications, including some antihistamines, sleeping pills, pain medications and anxiety medications, make the effects of alcohol much stronger. Fatigue, illness, dehydration and cannabis do the same. Servers cannot know what a guest has taken, which is one more reason to judge by behavior rather than by the number of drinks, and to slow down at the first signs rather than waiting for a count to be reached. Guests who arrive already showing signs of intoxication, perhaps after drinking elsewhere, are not served alcohol at all under Juniper's policy, however few drinks they have had at Juniper.

Promotions and specials

Drink specials can encourage rapid or heavy drinking, and Georgia and many cities restrict them. Juniper does not run all-you-can-drink offers, drinks-for-the-price-of-one deals or shot promotions; its specials are built around food pairings rather than volume, which also fits the house approach to pacing.

Water on every table

Water does not lower blood alcohol, but it slows drinking by giving guests something else to sip, and it reduces dehydration. Servers bring water to every table when guests sit down and keep refilling it, and bartenders put a glass of water next to every second drink at the bar.

Bartender standards

Consistent pours make counting standard drinks possible. Juniper's bartenders use measured jiggers or a calibrated pour spout for spirits, standard pour lines for wine, and set glass sizes for beer, so a cocktail, a glass of wine or a pint always contains the amount the menu says. Free pouring, where a bartender guesses the amount, makes drinks stronger and less predictable and is not allowed at Juniper.
