That's the article's point. My point is, by all means, be habitually rude to people. Makes my life easier when I'm behind you in line. Thanks!
You are not thinking this through. Ally yourself with four or five rude people and get them to stand in front of you in the line. Then you get some tickets for the next plane and split them with the rude people.
Then you end up trapped on a plane, surrounded by rude people. Sweet!
