One morning, I met a customer (顾客) in my shop .He wanted to buy some new clothes. First, I gave him a pair of trousers. He put them on to try, then took them off and gave them back to me and said, “No, give me a coat instead.”

    I gave him a coat and told him, “This one is worth as much as the trousers.” To my surprise, he took the coat without saying a word and walked out of the shop with it .I ran quickly after him and said , “You haven't paid for that coat!”

    “But I gave you the trousers for the coat,” he said. “They are worth the same as the coat, aren't they?”

    “Yes,” I said “But you didn't pay for the trousers, either!”

    “Of course, I didn't!” answered the man. “I did not take them. I am not foolish! Nobody gives things back and then pays for them.”
