I might worry about ordering from that place again. He probably has friends still there. She is probably getting someones balls rubbed all over her pizza.
I always make it a rule to be very nice to anyone who serves me food.
I have been with my wife out and she was going to complain about the service. I had to explain why it isn't always the best idea to complain BEFORE you get your food. Waiting untill after can be the difference between just bad service or spending all day in the bathroom.
