Salesman: Good morning, see anything you like?

John: Not yet, I’ll look around first…Excuse me, could you show me a pair of running shoes? Are any of these on sale?

Salesman: The price of the Reeboks won’t change, but the Nikes go on sale this afternoon:25% off. That’s a good deal.

John: No, I don’t like Nikes at all.

Salesman: Well, why don’t you try on this pair of Reeboks and see how they feel?

John: Okay. But I think they are going to be on the small side. Oh, there, I’m afraid are a bit too tight. Do you have a size 24?

Salesman: I’m sorry, they’re all sold out. But I’ll be glad to order a new pair of you.

John: How long will it take?

Salesman: Three days.

John: Then don’t bother. Thank you anyway.
