Advice: always get cash in a real bank, not in a cashpoint in the street. Avoid ATM linked to a wall or convenience shop. If your card gets stuck in the machine for whatever reason, you will be able to go talk to the bank staff. This will be much easier than trying to figure out how to get it back otherwise.
