ServSafe Alcohol cheat sheet

Legal serving age in the U.S. is 21; serving or selling alcohol to anyone under 21 is prohibited regardless of who purchases it.

A person who buys alcohol for or supplies it to a minor commits a third-party sale/provision violation, even if the minor never drinks it.

Legal blood alcohol concentration (BAC) limit for drivers 21 and older is 0.08%; commercial drivers are held to 0.04%.

Zero-tolerance laws make it illegal for drivers under 21 to operate with any measurable BAC (commonly 0.00-0.02%).

Dram shop laws hold a licensee civilly liable when a clearly intoxicated or underage patron is served and then causes harm.

Licensees must verify age with a valid, unexpired, government-issued photo ID; expired IDs and non-photo IDs are not acceptable proof.

Selling alcohol without a valid license, or outside permitted hours, is a licensure violation subject to fines, suspension, or revocation.

Intoxicated persons may not be served; continuing service to a visibly intoxicated patron violates the law even if the patron is of legal age.

Employees who serve alcohol may be personally liable and fined for serving minors or visibly intoxicated guests, in addition to the establishment.

Standard drink equivalence: 12 oz regular beer (about 5% ABV), 5 oz wine (about 12% ABV), and 1.5 oz distilled spirits (about 40% ABV) each contain roughly 0.6 oz of pure alcohol.

BAC rises faster with higher-proof drinks, rapid consumption, drinking on an empty stomach, lower body weight, and being female; food and time slow absorption.

The body metabolizes alcohol at roughly one standard drink per hour; nothing (coffee, cold showers, food) speeds this rate.

Measure spirits with a jigger or shot glass; free-pouring produces inconsistent and often larger pours that raise intoxication risk.

Offer food and water alongside alcohol; food slows alcohol absorption and water reduces dehydration effects.

Use a written or mental drink-count log per guest to track consumption; set a house limit (e.g., 2-3 drinks) and stop service at that point.

Check ID before the first drink is served, not after; this prevents underage service and establishes a record of verification.

Refuse service politely and firmly when a guest shows signs of intoxication; offer food, water, or a ride instead of another drink.

Never serve alcohol to a guest who is already intoxicated, regardless of how much they have already consumed or how well they tip.

Common behavioral signs of intoxication: slurred speech, impaired coordination, stumbling, loud or aggressive behavior, and slowed reactions.

Physical signs include bloodshot eyes, flushed face, drowsiness, loss of balance, and vomiting; any of these warrant stopping service.

Judgment signs include inappropriate comments, mood swings, and difficulty following conversation; these often appear before obvious physical signs.

BAC continues to rise after the last drink; a guest may appear fine and become more intoxicated 30-60 minutes later.

Use the 'stop, assess, act' sequence: stop service, assess the guest's condition, then act by refusing alcohol and arranging safe transport.

Do not argue or embarrass the guest; use calm, private, non-judgmental language when cutting off service.

Arrange a safe ride (taxi, rideshare, sober friend) for an intoxicated guest; never let them drive or leave alone on foot in an unsafe state.

Document the refusal and any incident in writing, including time, guest description, and actions taken, for liability protection.

Notify a manager or supervisor immediately when a guest is cut off or when intoxication is suspected.

Prevention starts at the door: check IDs, enforce occupancy limits, and watch for signs of prior intoxication before serving.

Use a team approach: servers, bartenders, and door staff communicate about guests who are approaching their limit.

Handle conflicts by staying calm, keeping a safe distance, and calling a manager or security rather than physically confronting a guest.

Never physically restrain or fight a guest; call police or security for threats, weapons, or violence.

Remove or refuse service to guests who are aggressive, harassing, or disorderly; document the incident and notify management.

Watch for signs of drug use or drink tampering (unusual behavior, sudden collapse); call emergency services and preserve the scene.

Keep exits clear, control access to the bar, and avoid overserving large groups or parties to reduce problem situations.

If a guest refuses to leave, do not escalate physically; call law enforcement and record the event.

Report and document all incidents (refusals, fights, ejections, injuries) promptly and accurately for legal and insurance purposes.
