Sincere consultation, is it safe to be a waiter in a bar?

Many things are said to be very formal. You have to do what others say, and see how you adapt. It is very important for the guests to handle this matter well. There must be scum in the bar. Why not raise this question and see how to deal with it?

To put it bluntly, going to work in a bar is to coax guests and maintain their dignity, so learn to be smart.
