I don't know how it is. Whenever I go to a post office I always find myself in a line behind someone who has a lot of complicated (繁琐的) business to do. One day, I had to buy a couple of stamps, but I had to wait patiently while an old lady took ten minutes to finish a form that a child could do in one. Feeling that I could not stand waiting in my motionless (不动的)line any longer, I decided to join another one. It seemed to be longer, but at least it was moving. It turned out, to be the worst choice I had ever made. Not only had I lost my place in the first line but the one I was in slowed to a stop. I was greatly annoyed(恼火). When at last it was my turn, the clerk behind the counter stood up and pushed forward a printed sign, saying “ Position Closed”(停止营业) and without even a smile said, “Sorry, going to lunch.” yyu
