We've had sophisticated scams with our ATMs, whereby an "envelope" is put into the atm machine, that makes it appear your card has been swallowed. and someone from a distance, or using a camera, observes you entering your pin number aswell. So you leave the machine thinking your card has been swallowed, only for the the criminal to come and pick it up once you leave. And if you haven't shielded the panel when putting in your PIN, they have your number, and start emptying your account. So just be aware of any card slots that look strange, and cover your hand as you enter your PIN. Asides from that, though, I've never heard of ATMs in Europe being dodgy or anything like that. Maybe from a bank charges point of view?
