Was on a flight leaving from JFK a couple of months ago when a man was repeatedly asked to turn off his phone which he didn't - it kept ringing and he kept taking the calls. When we were streaming down the runway in the middle of take off he started talking on the phone again and was sticking his hand in the FA's face to try to keep her from grabbing it. This was, however, a flight from JFK to Hong Kong on Cathay Pacific in Business Class. I'm pretty sure that AA wouldn't tolerate this behavior for a second.
