What might indicate that a guest is becoming intoxicated?

A guest becoming overly chatty and loud is a significant indication of intoxication. Alcohol affects the central nervous system, leading to lowered inhibitions and changing behavior. When individuals consume alcohol, they may feel more relaxed and confident, which can result in increased sociability and extroversion, hence becoming more talkative or loud than usual.

In contrast, speaking quieter than usual might suggest someone is feeling shy or uncomfortable, which could be due to various reasons unrelated to intoxication. Consuming food without drinking does not necessarily indicate a level of intoxication; some guests might choose to eat regardless of their alcohol consumption. Ordering non-alcoholic beverages typically suggests that a guest may be avoiding alcohol altogether, rather than indicating intoxication. Thus, loud or overly chatty behavior serves as a clearer sign of someone who may have consumed too much alcohol.
