I have not experienced that with an ATM card, but twice in the past week, the person ahead of me in a line has left the cash register and left their bag behind. One I was not able to catch in the parking lot - I couldn't find them - but the other woman was starting to drive away and drove right past me, as I yelled "Lady! Hey, Lady!" and waved her bag of stuff. She quickly braked, and said "Oh, thank you! I would have been all the way home before I realized it! Thank you!" and I did go back inside to let the cashier know I had caught her.
