Thank you, 175 yuan.
Here you go.
Here is your change and your receipt. Do you have goods unpaid on you, sir
No, I don't think so.
I'm sorry I need to call the security to have a look.
There must be a mistake.
Sorry, sir, it's my job to make sure the goods are paid.
Wait, can you check these sunglasses I bought it in the second floor. I think they forgot to demagnetize it.
Sure. Ah. . . That's the problem. Have you paid for it
Of course I did. Here is the receipt.
Let me see. . . Oh, I am awfully sorry sir.
That's all right.
