Several years ago, I had an employee who did this kind of stuff. He would go through the menu, discuss the entrees with the waiter, order something with a few changes, and then SEND IT BACK. Almost EVERY time.

There was one time where the waiter brought out the food and the head chef came along - he was apparently thrilled that someone was so interested and knowledgeable as to make these requests. But this guy tastes it and wants to send it back, and it becomes an argument, and the chef throws our whole party out of the restaurant. Oh, that chef was steamed.

This guy would do the same thing with wine. He'd order a nice bottle, and before it even arrived he'd say he was going to send it back - and he did. When a good sommelier would challenge him (that the bottle wasn't corked), the guy would just say that he didn't like the wine, and that's that.

It got to the point that no one on my staff would go out to eat with this guy because of this behavior.

He eventually left the company to start his own firm. I can only imagine what his clients must have thought at meals with him.
