Which term should be used when describing a customer that needs to be refused service?

The term "impaired" is the most appropriate choice for describing a customer that needs to be refused service. In the context of server training, "impaired" generally refers to someone whose ability to make sound decisions or judgments is diminished, whether due to alcohol, drugs, medical conditions, or other factors. This term encompasses a wide range of scenarios where a customer is not in a suitable state to receive service responsibly, particularly in hospitality settings where safety and compliance with legal regulations are paramount.

When referring to an intoxicated individual, while they may indeed be impaired, the term "intoxicated" specifically addresses alcohol consumption. This narrower focus makes it less applicable, especially when other substances or conditions can also lead to impairment. "Sober" would indicate a lack of intoxication and therefore would not apply to someone needing to be refused service. Similarly, "uninhibited" implies a lack of restraint but does not necessarily indicate that a person is in a condition requiring service denial; it could simply describe someone's expressive or carefree nature without the context of impairment. Thus, "impaired" accurately captures the essential reason for refusing service based on the broader aspects of a customer's capacity to engage responsibly.
