What is an appropriate action if a server witnesses a stress or harassment incident related to alcohol?

Intervening if safe and reporting the incident to a manager is the most appropriate action for a server witnessing a stress or harassment incident related to alcohol. This choice emphasizes the importance of ensuring the safety of all guests and staff while adhering to professional protocols.

When a server encounters a situation involving harassment or stress, it's crucial to assess whether it is safe to intervene. If it is, taking a proactive step could help de-escalate the situation and protect the well-being of everyone involved. However, the server also has the responsibility to inform a manager, who is trained to handle such incidents appropriately. This ensures that there is a formal record of the behavior, which can lead to further action if necessary, such as addressing the behavior with the guest or implementing preventive measures.

The other options may not adhere to best practices in handling harassment or stressful incidents. Ignoring the situation could allow it to escalate, potentially putting others at risk. Discussing the incident with other guests could lead to misinformation or escalate tensions. Confronting the guest directly might further provoke the situation, putting the server and others in harm's way. Thus, the correct response prioritizes safety, professionalism, and accountability.
