The homeless, right?
I wish! This group made very demanding customers. Nothing was ever right, they sent things back a million times, and often they had ordered things from the menu that they didn’t understand and they would be very upset when the dish arrived. The manager would always take it off the tab for them, however, anywhere I worked, but then management would criticize the wait staff for “letting” people order something.
Sometimes, when I realized that people were ordering a dish that they weren’t going to like, I would discreetly attempt to describe it so that we could avoid this situation (without insulting the customer, of course). But it was difficult. Some people understood and some didn’t.
