I deliver pizzas and this person began to complain that their pizza (which had a bunch of veggies and meat) had no meat. He also insisted that he paid via credit card when the reciept clearly was for cash. He yelled at the people in the call center and I had to point to the meat for him. I pointed to ham, sausage and hamburger meat. He demanded another pizza but the call center person said that if he continues to act this rude, we will no longer serve him. He got mad and paid just enough for it. I was now in a bad mood but as I was in my car about to drive away, his wife was nice enoguh to give me a fifteen dollar tip for the trouble her husband caused.
