Last weekend I went shopping for a new pair of jeans. There were so many different types that I didn't know which one to choose.a shop assistant come over and asked me if I needed any help ."why don't you label a few pairs?" She suggested."good idea," l replied."then I can see if they fit me ." "there's a changing room just over there," she said. After deciding which pair l like best, I checked the try on ' to see how much they cost. They were quite label si l decided to but two pairs of them. I took them to the cheap can I pay by cheque or credit cards I asked."yes,of course," he replied."would you like me to put your receipt in the bag? You should keep it in case you want to bring them back.
