I really don't like the hat either. Think it looks goofy, it's bulky and uncomfortable, and when I take it off to eat, I get goofy hat hair. Not to mention, it's easy to lose.
That said, it recently started being heavily enforced at my company after Colgan flipped one over in Buffalo (company thinks hats will prevent similar accidents). Now I just wear it all the time because I don't ever need to have a CP ask me "where's your hat." Don't want to deal with it. Better to just wear the damn thing because it's better than getting on someone's "list" for something that trivial.
And to lose a dreamshot like Hawaiian over it? Gimme a break.
