Which statement best represents a violation of alcohol service laws?

Providing service to an intoxicated patron represents a violation of alcohol service laws because it poses serious risks to the health and safety of that individual and others around them. Most alcohol service laws are designed to prevent overserving, which can lead to dangerous situations, such as drunk driving, health emergencies, or aggressive behavior. Serving alcohol to someone who is already intoxicated undermines responsible alcohol service practices and violates regulations aimed at promoting safety in establishments that serve alcohol.

The other options do not violate alcohol service laws in the same way. Serving alcohol to someone with a valid ID is generally legal because the ID verifies that the person is of legal drinking age. Refusing service to a minor is an appropriate and responsible action, as it is crucial to prevent underage drinking. Offering discounts for large groups is typically allowed under alcohol service laws, as long as responsible service practices are followed.
