You might be an airline pilot if......
.....you are a grown middle aged man but you still have to request permission to go to the bathroom when you are at work....
......you've ever been waiting outside the hotel for the van in the dark at 0430 waiting to start your day while watching drunken partiers stumble down the street as they finish their day....
....you've ever read the dispatch paperwork at the podium to find you've been given the jet with several bizarre and intricate MELs, the destination WX is near mins and right at that moment, a guy in an ill fitting cheap sport jacket comes up to introduce himself and before he says a word you know who he is and who he works for and think...."Awww crud, not today!"
