Are you a UA employee? If not, then butt out and mind your own business. I wouldn't bring my own liquor on to the plane (seems kinda trashy) but if you did this to me or if I saw you do it to someone else I'd definitely give you a piece of my mind. There is nothing worse than having to deal with some busybody pax on a flight. Don't you have anything better to do with your time than police others behaviors? HUGE HUGE HUGE HUGE
