This morning I go to the shop to change the coat I bought yesterday. But the salesgirl treated me very cold. At the first, she said the coat wasn't selling in the shop, and then she said I had made it dirty. She gave me several different excuse and refused change the coat. So I got angry and argued with him. Just then the manager turned up. He asked that was the matter. After I told him the whole story, he said sorry to me but exchanged the coat for me. Satisfying, I said goodbye to them and took the new coat home.
