There's always the guy showing up at the last minute that needs to sit in 33F. Screws up everything.

>IIRC, MythBusters also showed that people generally have a desire not to be shown as wrong, so they "defend" their initial choice and stick - even when they've heard this proof. While we've diverged onto the general topic of dumb things people do - I saw a demonstration of how to board passengers on a plane. Start at the back - window seats first. Even #'d rows. Then odd rows. The middle seats, even then odd, then aisle seats. With no practice this method beat the industry "standard practice" by two minutes. Unfortunately not adhering to the program leads to blockages. Standard practice is to assume we're all no smarter than ants and let us figure things out as we board.
