W: Did you find everything ok today?

M: Yes, I did. By the way, in case there is a flaw in this CD player, can I return it?

W: Yes. But you must return it within 30 days.

M: Is there a charge for that. I know other stores have a restocking fee.

W: There will be no arge at all. However you must show us the receipt. Could you sign it here, please?

M: Thank you.

W: All right. Keep you receipt. If something comes up, you can show it to us and we will give you a refund.

M: Thanks. I'll put it in a safe place.
