A: Hello, I'd like to check in.
B: Do you have a reservation?
A: Yes, George.
B: Sorry, we don't have anyone under that name with a reservation.
A: What about Mr. Black?
B: Sorry, we don't have it, either.
A: What's wrong? I did make the reservation last week.
B: Wait a moment. I'll check it again. I'm really sorry. I can't find it.
A: How are you going to deal with it?
B: That's all right, sir. We still have rooms available.
A: OK. I want a single room with a bath.
B: Yes, sir. Is the fifth floor OK?
A: Yeah.
B: So Room 507 with 24 hours hot water.
