Behavioral cues help servers of alcohol by indicating if a customer is intoxicated or approaching intoxication. This allows servers to regulate alcohol intake and prevent excessive drinking.
Step-by-step explanation:
Behavioral cues can greatly help servers of alcohol in various ways. By observing the behavior of customers, servers can determine if they are intoxicated or approaching intoxication. This allows servers to responsibly regulate the alcohol intake of customers and prevent excessive drinking. Behavioral cues such as slurred speech, stumbling, aggressive behavior, or difficulty maintaining balance can indicate intoxication. Servers can then refuse further service to the customer or take appropriate actions to ensure their safety.
