This happened to me before. I pullled up to the drive-thru ATM and it was beeping (it does that if you leave your card in there) and there was the card sticking out of the little card slot. I took it out did my business and then took the card into the bank. Got a very small thank-you and left. I would want mine returned as well, but given there is not much money in there it wouldn't be worthwhile to steal any of it.
