Some people!!!!! (Rant)
I used to work with a guy that bought a beater from a co-worker in the middle of winter, then come summer wanted his money back because the a/c didn't work. This same guy had a Subaru that needed a timing belt, he bought a second Subaru for the timing belt, depending on when it was made it could have been one of three different timing belts. This same guy would save his did fireworks and take them back to the fireworks stand for a refund.
