What is a sign that a customer might be experiencing alcohol poisoning?

Slow breathing is a critical sign that a customer might be experiencing alcohol poisoning. When someone has ingested a dangerous amount of alcohol, it can severely slow their body's functions, including breathing. Normal breathing rates range from 12 to 20 breaths per minute, and if someone is breathing fewer than eight times per minute, it can indicate a serious medical emergency. Alcohol depresses the central nervous system, which can impair the body's ability to function normally, leading to slow or irregular breathing.

Monitoring someone for this symptom is crucial because it can help identify when they require immediate medical attention. Recognizing alcohol poisoning early can potentially save a life, making it important for anyone in the service industry to be aware of this and act accordingly.

Other signs and symptoms of alcohol poisoning may include confusion, vomiting, seizures, and unconsciousness. However, in this multiple-choice context, slow breathing serves as a key indicator that needs prompt action, making it the most appropriate answer.
