On the flight last night ATL-ORD, the FA announced during takeoff/landing that passengers with iPads and iPhones need to turn off the devices completely and explained exactly how to do it.

As the FA was walking down the aisle, she asked the passenger across the aisle from me if he would power down his tablet completely. The guy in the seat said it was powered down. She corrected him and said it was not and told him what button to press and hold to do so. This miffed the passenger and he held the tablet up to show her the blank screen. She reached to it, pressed the button on the top once, and it immediately illuminated. This apparently called his bluff and he went into a tirade, wanting to know what was wrong and why he was being treated like this. The FA informed the passenger politely that this was FAA and AA rules, and that she was obligated to enforce them if she witnesses non-compliance. At this point the passenger went off. "I've never had anyone do this before. I'm Concierge Key and you should really be treating me better! Can you give me your card?"

The FA came back with a slip that had all her information and kindly handed the passenger his sport coat before landing. I don't think this FA should take heat for doing her job. I'm considering writing a note to AA complimenting the FA for being professional in a heated moment.
