What is the man complaining about?

W: Hello. How can I help?
M: I’m in room 423 and my luggage should have been taken to my room but it’s not there.
W: Oh, dear. Room 423?
M: Yes. I’m not happy at all about this. My valuables are in my case and if they are missing there will be trouble.
W: Let me find out where your luggage is. I’ll just be a minute. I’ll check with the bellman.
M: Please be quick.
W: I’ve spoken to the bellman and he accidentally took your luggage to room 432.
M: What an idiot!
W: He’s going to put them in the right room straight away.
M: Good, I thought you had lost them.
W: I’m sorry for the inconvenience, sir.
M: You should be.
W: Can I offer you a complimentary bottle of wine as an apology?
M: That would be very good.
