HAWK, the world is full of these people.
1. I am an important businessman, and must keep talking to my company.
2. I am a teenager in love, and I will lose her if I don't text every 15 minutes.
3. I am rich, and airline rules don't apply to me.
4. I am [insert National character here] and therefore don't care anyway.
5. I am really VERY stupid.
They fly on every aircraft I have ever been on.
6. I am going to stand in the aisle and spend 10 minutes putting my bag in the overhead so that nobody else can get on the aircraft.
