Casher: Thank you, 175 yuan.

Terry: Here you go.

Casher: Here is your change and your receipt.

(Just as he leaves, the infrared alarm burps.)

Casher: Do you have goods unpaid on you, sir?

Terry: No, I don't think so.

Casher: I'm sorry I need to call the security to have a look.

Terry: There must be a mistake.

Casher: Sorry, sir, it's my job to make sure the goods are paid.

Terry: Wait, can you check these sunglasses? I bought it in the second floor. I think they forgot to demagnetize it.

Casher: Sure. Ah…That's the problem. Have you paid for it?

Terry: Of course I did. Here is the receipt.

Casher: Let me see…Oh, I am awfully sorry sir.

Terry: That's all right.
