B: Do you have a receipt with you?

A: Yes. Here you are.

B: Thank you. Do you want your money back?

A: No. Can I exchange it for a bigger one?B: I'm afraid this is the biggest size we have.

A: Oh. That's too bad.

B: Maybe you would like to try this one with a willow pattern. The price is the same and it's bigger.

A: All right.
