Describe a time when you had to handle a situation outside your comfort zone.
A safe zone is an area that is difficult for each person to break. It will make people feel safe there and not want to come out. But a good waiter needs to have great skills in breaking their own comfort zone, in order to provide the best service.
Interviewers use this question to gauge how you respond to a situation that is outside of your comfort zone in order to gain a feel of how you handle difficulties and strange circumstances. Show them that you can handle new challenges and take on tasks, even when they are outside of your comfort zone.
Example:
One hectic Saturday night, I once had to fill in for a coworker who called in sick. I was forced to fill in as the bartender for the evening despite though I usually work as a waitress. As I had never made beverages before, I was really concerned about making mistakes or giving the wrong instructions. Yet, I was aware that the restaurant was depending on me, and I didn't want to disappoint my group.
I therefore made an effort to learn as I went and sought assistance from the other servers and bartenders. Although it was undoubtedly outside of my comfort zone, I managed to pull it off, and the evening passed without a hitch. It was a terrific opportunity for me to pick up a new talent, and I was quite pleased of myself for rising to the occasion and handling the task.
