Amen.... I fly around 4 times a yr and can honestly say that I have witnessed rude behavior from passengers many times. I hate it when the plane is taxi'ing in and people start getting up to retrieve their ''oversize'' bags from the overhead bins. They usually bump their bags into the passenger sitting directly below or fumble around in the aisle, therefore, coming into contact w/other passengers.

Last time I flew, the attendant politely asked a man to turn his laptop off 3 times and the last time, he slammed it shut and swore at her. Uncalled for.... 2 sides to every issue, I guess.
Obviously, he snapped.
