Turned mine off in the theater waiting for some g rated animated flick my kids wanted to see.....when they said to on the screen..."be polite and do it".....thing made a noise louder than my regular ring.
Some Birkenstock wearing long arm pit haired soccer twit gave me the evil eye......had to have one of my daughters tell her I was turning it off and not taking a call from my stockbroker....otherwise I was about to dickslaphearazz.....
I'll lose the phone when I move to Tahiti and the island girls come at my whistle....but I'll be polite in the interim....
