[speaker001:] Good coming, sir. What can I do for you?
[speaker002:] I'm Mr. Bob, Room 309. I'm checking out today. Can I have my bill now?
[speaker001:] Certainly. Please wait a moment. Here is your bill.
[speaker002:] What's the 30 yuan for?
[speaker001:] This is the charge for your laundry service on Nov. 20thA
[speaker002:] But I did't take any laundry service during my stay here. I think you have added someone else's.
[speaker001:] Would you mind waiting a moment while we check it with the department concerned?
[speaker002:] I don't mind waiting as long as we get this straightened out.
[speaker001:] I'm very sorry, Mr. Bob. There has been a mistake. We'll correct the bill.
[speaker002:] It doesn't matter. Here is the money.
[speaker001:] Thank you very much. Hope to see you again.
