Two thoughts:
1) You should have been off the phone before the doors closed. While we all agree that the rules SUCK and are RETARDED, they are the rules. If we (meaning the pseudo-airline-literate) ignore the rules and chat when we shouldn't, that just gives more motivation for the unwashed masses to ignore them also, and board before us even though they're in seat sixty-eight Q.
2) This woman is an idiot, and like the rest of the idiots on our beloved UA flights, must be ignored and shot Evil Dirty Withering Looks Of Shameful Beating the entire flight.
2a) much good Karma to you for kicking the dumb .....'s seat the whole way.
