Which of the following represents an effective method in the S.I.R. protocol?

The focus of effective methods in the S.I.R. protocol is on proactive measures to ensure responsible service of alcohol. Surveying the area for potential hazards is a good practice but is not specifically part of the S.I.R. protocol. Similarly, rating a customer's emotional state or checking identification after serving do not align with the core objectives of S.I.R.

Interviewing the customer before every drink order embodies the principle of engaging with guests to assess their level of intoxication and ensure responsible alcohol service. This method allows staff to gauge customer behavior and make informed decisions about serving alcohol, thus promoting a safe environment for everyone. This proactive approach is crucial for identifying potential issues before they escalate and plays a vital role in effective alcohol management.
