Shop assistant: Hi there. Do you need any help?
Ann: Hi. Er … I really like these slippers. How much are they?
Shop assistant: Oh … they’re 10600AMD.
Ann: OK. Do you have them in a 34?
Shop assistant: I’ll have a look for you.
Ann: Thanks.
Shop assistant: Oh … what color would you like?
Ann: Orange, please.
Shop assistant: OK, just a moment, please. We’ve got a 34 in red, but not in orange.
Ann: Oh … do you have size 33 in orange?
Shop assistant: Yeah, sure. Do you want to try them?
Ann: Yes, please. 
Shop assistant: How are they?
Ann: I like them, but they’re a bit too small.
Shop assistant: Do you want to try the red ones in your size?
Ann: Mmm no thanks. I don’t like the red ones too much.
Shop assistant: Ah, OK. I’m sorry about that.
Ann: Don’t worry … Bye.
Shop assistant: Thanks a lot. Bye now.
