When I first read the story, I thought, "How rude, immature, unprofessional, and dangerous a response by a flight attendant." I read it expecting to see that the guy was arrested. I wasn't disappointed.
Now I'll be the first to agree that flight attendants often have lousy jobs, and having to deal with customers with bad attitudes just makes it lousier-especially when they can't eject them from the plane. And the passenger in question was rude and her misconduct could have caused danger to everyone on the flight, no doubt about that. But he chose an extreme and completely inappropriate way to deal-and deserves the consequences. That he's getting 15 minutes (and more) of fame and support out of this really annoys me.
