#Person1#: Can I help you?
#Person2#: Yes. How much are these T-shirts?
#Person1#: They are 12 dollars 50 cents each.
#Person2#: I like the green one, but it isn't big enough. Have you got a larger size?
#Person1#: Just a minute. No. I'm sorry. We haven't. What about the black one?
#Person2#: No, it's too dark. I prefer something lighter, yellow or pink.
#Person1#: How about the pink one?
#Person2#: Yes, that's nice. I'll take it.
#Person1#: That's 12 dollars 50 cents then please.
#Person2#: Here you are.
