I went to a shop to buy a jacket one Sunday. It is famous one where there are a variety of clothes. I looked all around and finally find an attractive jacket. When I was asked the price, the assistant said, "Seventy dollars." He added that if I paid by cash, he would give me a discount – ten percent off the fixing price. I thought it was so expensive and started to leave. As I was left, he grabbed me and said, "Okay. Forty-five dollars." Delighting, I bought the jacket. However, when I got home and tried on my new jacket, I realized that anything was wrong with it. It had a pocket where wouldn't open. I was speechless and looked at it in amazement.
