The customer can’t have a refund because

M: Excuse me! I’d like to return this sweater for a refund. The first time I washed it, it shrank at least two sizes.
F: Oh, that’s a clearance item. But don’t worry. It’s also refundable within 7 days after purchase. Do you have the receipt?
M: Here it is.
F: Sorry, I am afraid I cannot refund this, because you bought it 8 days ago.
M: Oh, I didn’t realize that.

F: Sam, I couldn’t figure out why the ending balance on 2007 didn’t match the beginning balance on 2008.
M: When I checked, it was matching. How much is the difference?
F: The amount is exactly $42, 000.
M: Oh. I got it. We opened another bank account at the end of 2007. I might not have included that information.
F: That makes sense. I’m just glad it wasn’t my miscalculation.
