I remember a much less spectacular, but related 'hack' that worked here in the Netherlands until it was patched years ago. The trick was to withdraw 125 guilders from your bank account (this was before the euro), which would be presented to you as a f25,- and f100,- note. You could carefully take the f100,- note, but let the f25,- sit in the slot. After a while the ATM would detect that the money had not been taken from the slot, and take the money back. Your bank account statement would show a withdrawal of f125,-, and then a deposit of f125,- shortly after corresponding to the money being taken back by the machine. Of course, you couldn't do this too often before they caught on to you.
