No matter what the truth is here, I can say that, after working in restaurants for many years, it's never wise to trash out the people who are preparing your food, regardless of the circumstances.

that, sir, is an exceedingly wise comment.
Nothing (for me) beats the story of a friend, working at a steak restaurant in a beach resort, who brought a steak not cooked well enough back to the Asian chef/manager, who proceeded to remove his manhood from his trousers, slap the steak with it a few times, and threatened to fire the waiter if he did not return the steak as it was to the patron.
I've learned to appreciate slightly less than medium rare (my preference) steak.
