My wife and I took a close friend (who I might add some would say has class based on his Cambridge undergraduate and doctoral degrees ) to Alain Ducasse New York for dinner a couple years ago. During one of the early courses his cell phone went off. The maitre de quantum teleported from wherever he was to our tableside. French Foreign Legionnaires came down from the ceiling as backup. The maitre de apologized for forgetting to offer to store my friends phone during the dinner but offered to do so immediately. My friend said that wasnt necessary but he would turn the ringer off. The maitre de suggested it would be best to turn the power off on the phone instead. The Legionnaires locked and loaded their weapons, my friend complied. All smiled. The Legionnaires disappeared into the ceiling. The maitre de bowed and left to tend to other guests.

That is what happens at $50 per person restaurants!
