What sign might indicate that a customer is unaware of their appearance when intoxicated?

A customer showing signs of being unaware of their appearance when intoxicated would typically exhibit characteristics such as mussed hair or disheveled clothing. This can indicate a lack of attention to their grooming, which is often associated with impaired judgment and decreased self-awareness that can occur with intoxication.

In a social setting, individuals who are well within themselves and sober are usually more conscious of their appearance and how they present to others. Thus, signs like disheveled clothing can serve as a red flag for staff, suggesting that the customer might not be fully aware of their state or how others perceive them.

The other possibilities—dressed impeccably, wearing formal attire, or frequently looking in the mirror—do not suggest that a person is unaware of their appearance. In fact, those options indicate an awareness or concern about how they present themselves, which is less likely when someone is intoxicated.
