When ever i stop by the gas station on my way to work I allways peek in the cash drawer and ask fot any halfs or large dollars they may have, to date ive gotten four IKES and a couple franklins. The girl who works there is so used to me doing it now she sets them aside whenever she gets them knowing that ill pop in and ask. My best haul was a whole roll of buffs, nothing terribly exciting in the roll, but I only paid face value for them
