I try to not to swear in the company of anyone other than friends and family as I feel it drops you to whomever you're disagreeing with's level.
I don't consider the term used in the OP swearing however, they say it on TV just fine =)
My reply to the guy from the OP would have been "Long enough to know only a self important dick spreads his jacket out in the overhead bin on a regional jet"
anyone who doesn't want their jacket wrinkled should put it on top of their bag, their lap, or fly in FC and have it hung up =)
