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.
