Change something in a shop

G: Hello. Are you OK there?

C: Yes, hi. I was given these jeans as a present but they're too big. Is it OK if I change them?

G: That should be OK. Have you got the receipt?

C: Yes, here you are.

G: OK. Well actually, we've sold out of those jeans, I'm afraid. You can choose something else if you like.

C: Oh, right. Can I try these things on?

G: Yes, sure. The changing rooms are over there.

C: What do you thing of this skirt? It isn't too long is it?

G: No, i don't think so. It's really cute.

C: OK, I'll take it then. Thanks
