It's not just airline passengers, but in society in general there is no sense of decorum, courtesy or common decency. Take your family to a nice restaurant and some idiot will be sitting nearby letting the expletives fly because they think they're the coolest in the place and have a right to say and act how they want. We blew off our parents and grand parents when they wanted us to learn a few manners, and now we're paying the price for it. No one even thinks of saying please, excuse me, or thank you anymore. Just FU because I think I'm better than you. This is a trait that crosses all lines of gender, age race, and social background. Learn to live with it because that's just the way life has become.
