i used to be a manager at a subway with a very busy lunch rush with lines out the door. it was pretty much business people with a small amount of students from the college down the road. I don't have time to be polite and wait for these customers who talk on cellphones, due to the fact that our lunch hour was super busy. so if someone was one the phone i would just loudly ask what they wanted until they answered me. If they didn't answer, i would just ask the next person, and that cellphone talking customer would be pushed out of line. I felt bad being rude to this person, but all these other people shouldn't be late coming back from their lunches just because somebody wanted to talk on their phone. My business isn't going to suffer just because you wanted to talk to your friend or husband on lunch. wait four more hours and call them then. or wait until you done ordering your fucking food.
the worst one was, "oh im on the phone with my friend at the office and i'm waiting for an order from them," and then peice by peice over the phone, you make their sandwhich. and then at the end they tell you they want another sub with a line of ten people behind them. grow up, write down that order before you leave the office, hand it me, and let me make it.
