I remember some reality show a while back with Richard Branson where in the beginning people were selected to pass a bunch of tests and whoever won would be his assistent or something like that. Anyway, in the first espisode, he dressed up as the taxi driver and it was really funny to watch as the cocky arrogant candidates pretty much thumbed their noses at the "elderly" taxi driver and didn't offer to even help as the guy was having a hard time unloading their bags out of the cab.

What an awesome way to judge someone's character! I don't remember much of that series, but I remember that. It always pays to be nice and courtious and respectful to everyone you deal with.
