It all comes down to the old truth which my mother told me years ago 'You should never p*ss off the people who serve your food'
Not that I would ever condone it, but I come from a 5 star dining background.. never, EVER be rude waitstaff in a restaurant (or cabin crew on an aircraft for that matter) They control it all
Again, I would never condone, or do it, but it still goes on today (in both restaurants and in the air).
You would be very surprised what happens to your food when you 'go-off' at a waiter, even in a 5 star dining restaurant !!
