W: Good morning, Mr.Jacob. Is everything all right?
M: No, it’s not. Someone’s stolen some of my valuables—two rings and a gold necklace.
W: I’m very sorry to hear that, sir. Where were they?
M: In my room. And the door was locked. It can only be one of your staff. I want my things back. And fast.
W: Well, I Call certainly understand that you’re upset about losing them and we’ll do all we can to help. If they really are missing, it’s a matter for the police.
M: What do you mean, if they are missing? I told you they were.
W: Yes, Sir. But first I’ll have one of the housekeeping staff look through your room in case they’re still there. But I must say that we can’t be held responsible. You should have deposited the valuables with Reception. It says so on the Key Card.
M: That’s not good enough. I want to see the manager, immediately.
W: I’II be glad to call the duty manager for you, sir. But he’ll certainly say the same. We have clear instructions about valuables and we must follow them.
