When I worked at the pizza shop long ago we had this regular customer who every time we delivered to would call and say something was wrong. She did it every single time she ordered and yelled at us but continued ordering anyway. One night she called to make her order which was always a pizza, some hot wings and a salad and we knew that she was going to call back so we made double triple sure everything was okay. Lo and behold she called again complaining that her salad had no olives, onions or anything. It was just lettuce. I knew exactly what the problem was so I drove all the way to her apartment. Told her to hand me the salad so I could fix it and she said just give me the right one and I said just hand me the salad so she gave it to me. I flipped it over, opened it, showed it to her and she slammed the door in my face. That was a good night.
