What should be the first step if a customer has passed out from drinking?

When a customer has passed out from drinking, the first step should be to call for medical assistance. This is critical because passing out can indicate a serious medical condition, such as alcohol poisoning, which can be life-threatening. Professional medical help is necessary to assess the person's condition and provide appropriate care.

Calling for medical assistance ensures that trained professionals can evaluate the individual's needs quickly. They can perform necessary interventions that non-professionals might not be equipped to handle, which is vital in potentially life-threatening situations.

While it may be important to ensure the individual is comfortable and safe, such as checking hydration status or providing a supportive environment, these actions cannot replace the need for professional medical evaluation and intervention, especially if a person is unresponsive.
