To be honest, I really don't either, in principle. But since Mr. Ex is a restaurant manager, I hear all kinds of horror stories about the kinds of things he has to deal with, smooth over, and put up with...all in the name of "the customer is always right." I guess that that colored my perceptions somewhat when making that statement, so I make full disclosure, now. :)
I used to work in the rest. business too (as a servr). I can imagine Mr Ex's horror stories quite well.
