I've always wondered about the turn-down service in hotels.

At a very top-end hotel, OK, maybe. You come back in the afternoon, and the bed is covered and protected, go out, come back in the evening, and it's all ready for you just to slip into bed (covers, lights, tidiness, etc.)

However, I was in a Crowne Plaza last night, working, and got a knock on the door for turn-down. The cleaner came in, folded over the corner of the quilt, handed me a mint, and left.

What exactly is the point of that?
