If that's the knife sharpener, take him around to the back.

And now, every single year he goes and, at some point, he moves the pencil sharpener and every year, the guys moves it back.

As a matter of fact, I have a friend who goes annually to his accountant with his wife and about 10 years ago by chance, he leaned on the accountant's desk and he moved the guy's pencil sharpener just a tiny little bit and immediately, the guy moved it back.
