Yesterday I bought new coat in a shop. When I came back home,I found
it so big for me . This morning , I went to the shop and change the coat
I bought . But the sales girl in the shop treated me cold . Firstly ,
she didn’t admit that I buy the coat in her shop . Then , she said I
made it be dirty . So I got very angry but quarreled with him , pointing
to the rules on the wall。 Just then , a manager turned up . He said
sorry to me and they changed other one for me . At last , I said goodbye
to them and took the new coat home happily .
