The problem is that it is innappropriate and unprofessional for an employee to call a customer a fat girl to their face, and if it is there in plain writing on their bill it is essentially the same as saying it. If they tag orders with descriptive words describing the customers I don’t have a major problem with that, but it should be impossible for it to print out. In a restaurant I don’t really get it, because aren’t the tables numbered? And, aren’t there a lot of fat people in the restaurant? Maybe they live in a skinny city and there aren’t many fat people.
