In my local paper was a (humorous) column about the columnist's family vacation in Mexico. When using an ATM upon arrival the ATM “ate” his card. When his adult daughter arrived later, same thing happened to her. He found out that in Mexico ATMs are fixed so if a card isn’t retrieved within a short time, the machine sucks the card back in. When machine is opened at a later time by an employee, they cut up the card.
This wasn't in Europe, but maybe it is something to consider. It could be coming soon to an ATM you will be using. Remove your card asap after your transaction is completed. And another reason to try to use only ATMs at an open bank where you can get help if needed.
