I went through the cafeteria at school and paid for my food (cup of chili and yogurt). For all of two seconds I thought the woman who gave me my change had said, "Here you go, sir." I have had problems with black female sales clerks in the past. Then my brain caught up and I realised she had really said, "Here you go, suger." I fealt very glad that I had trained myself not to react when I get "sired." Otherwise I could have really embarassed myself.
