It reminds me of a hotel I stayed at that had a stocked mini-fridge. Removing any item from the fridge resulted in an automatic, silent charge. Putting it back did not remove the charge. So if you simply took something out to check it in, or if you wanted to chill your own beverage, they counted that as consuming the item.
They removed the charges if you checked the bill and objected at checkout. But how many people don't look? I'm sure it generated enough revenue to pay for the sensors. No one is going to say it out loud, but false positives are the point.
