I suspect you are correct, and they run around scanning the license plates (as well as grabbing them on entry) because I've seen a lot of evidence that's becoming more and more common in overnight parking - aside from everything else, it makes the "I forgot where I parked a week ago" and "I can't find my garage ticket" customer service tasks somewhat easier to solve. But I've run into the same thing, and also seen multiple photos of my license plate come up on the cashier's screen while checking out of a couple of places.
