I was the next guy in line and the person before never took out his card so I could have pressed pretty much whatever amount I wanted and boom free cash. However I removed the card for him when I realized mine wouldnt go in and he came back to the ATM about 20 seconds after he had left looking for it.
I had a machine spit money at me, like no s***. I got $200 out, pulled it out, the flap closed then opened again and started spitting bills out, I think about $160 worth. It was inside a bank though, so the employess were on it right away. It was an ooooooooollldd machine in some little podunk town in eastern Alabama, but still a pretty cool experience.
