#Person1#: Good coming. What can I do for you?
#Person2#: I'm in Room 309. I'm checking out today. Can I have my bill now?
#Person1#: Certainly. Please wait a moment. Here you are.
#Person2#: Thanks. Wait... What's this? The 30 dollar for?
#Person1#: Excuse me... The charge for your laundry service on Nov. 20th.
#Person2#: But I did't take any laundry service during my stay here. I think you have added someone else's.
#Person1#: Ummmm...Sorry, would you mind waiting a moment? We check it with the department concerned.
#Person2#: No. As long as we get this straightened out.
#Person1#: I'm very sorry. There has been a mistake. We'll correct the bill. Please take a look.
#Person2#: Okay, here you are.
#Person1#: Goodbye.
