I always check the machine at our local Walmart and have got exactly one silver dime out of it up until a couple months ago. Walking past it one day I almost didn't look since we were already checked out and heading to the car. When I decided to have a peek the return slot was overflowing... When we got home and totalled up what I pulled out of it there was close to $27. All clad so I have no idea what caused it to be rejected of why on earth the guy who used it last never bothered to look but I'm not complaining. Since that day, zero... nada.
