What is the primary method to refuse service to a customer who is overly intoxicated?

Refusing service to a customer who is overly intoxicated requires a responsible and effective approach to ensure the safety of the individual and others. Offering them a drink of water is the primary method because it serves several important purposes. First, it helps to hydrate the individual, which can alleviate some symptoms of intoxication. This action also demonstrates care for their well-being, showing that you are attentive to their condition.

In situations involving intoxication, it's crucial to take measures that prioritize safety rather than exacerbating the issue. Providing water can also serve as a non-confrontational way to shift the focus away from alcohol consumption while subtly signaling that further alcohol service is not being provided. Engaging in conversation without addressing the situation or checking ID would not directly help in managing the intoxication level and could potentially complicate the scenario further rather than defusing it.
