JMHO . . .
I've worked in a few restaurant kitchens in my day. Let me put it this way . . . If your ears had a tendency to burn when cuss words were thrown around, then they'd be on fire from the time you hit the door 'til the time your shift ended (if you managed to make it through a shift, that is), some nights.
Having said that, I DO think that in a specialized situation like this --- where you are going to be taped and broadcast all over the country, etc. --- you might want to take that into consideration and clean it up. Just a little, at least. Nobody is expecting or asking you to be a saint (none of us are). But even though you may be the best chef/cook/whatever in the world, you don't really look as though you'd be somebody anybody would want to work around if every other word out of your mouth is having to be bleeped out. You come across as totally combative and --- even more importantly, to my way of thinking --- ignorant.
I think Andrew just might be interesting to watch. I liked that he didn't go off and make a big scene/issue about the missing deep-dish pan with whoever it was that took it. Right then wasn't the time to jawjack with the guy about it, and he recognized that, found a workable alternative and got his pizza out.
Good for him for handling it that way.
But all in all, it couldn't hurt him to clean up his mouth (at least a little) since he's on national TV, either.
