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: I need to go over the schedule for Wednesday’s workshop.
M: Okay. Here’s the schedule. The workshop will start at nine thirty.
F: Okay. Now, we had planned originally for the workshop to go until ten thirty, but now we have someone from the international center coming to speak to the participants on overseas promotion, so how about extending the workshop for half an hour?
M: Fine. Let’s change the schedule.
