Which method is effective for assessing if a customer is intoxicated?

Observing consistency in speech is an effective method for assessing if a customer is intoxicated because changes in speech patterns can be indicative of a person's level of impairment. Intoxication often leads to slurred speech or difficulties in forming coherent sentences, which can signal that a person has consumed alcohol excessively. By paying close attention to how a customer speaks—whether they are speaking clearly, whether their words are muddled, or if they are having trouble articulating their thoughts—servers can gauge whether the individual may be over the legal limit for alcohol consumption.

While checking identification can help confirm a customer's age and whether they are legally allowed to drink, it does not provide direct insight into their current state of intoxication. Similarly, providing multiple drink options or asking about their favorite cocktails does not aid in evaluating their level of impairment and could also encourage further drinking. Observing behavioral cues, such as speech, is a more direct and relevant approach to assess intoxication effectively.
