Lisa: Excuse me, I'd like to return this shirt.
Clerk: What's the problem with it?
Lisa: It's too small.
Clerk: Didn't you try it on before you bought it?
Lisa: As a matter of fact, I received it as a gift.
Clerk: Then you are sure it came from our store?
Lisa: Yes, I am pretty sure. Don't you sell this item?
Clerk: Yes, we do. I'm afraid we don't give a refund, but we can give you a credit towards another purchase in our store.
Lisa: No refunds? Well, in that case, I'll accept the credit.
