scams
i know a guy who picked an optometrist at random from the phone book. paid like $600 for an exam and a pair of contact lenses. dude you could have gotten contact lenses for $80 at this other place. but he absolutely refused to believe he'd been screwed. he argued his contacts were much better. (they weren't.) he gets multiple appointments. (which he has to pay for.) his arguments were incredible in their absurdity. how come people can't just say, ouch i got screwed? hang their head, and learn from their mistake? they can't. this is what allows scams to work time after time. people aren't willing to admit, even just to themselves, that they've been boned. and they get fleeced over and over.
