Forgotten card

If you accidentally leave your credit/debit card in an ATM, it will swallow the card after 10 seconds of inactivity and destroy it. You will then have to cancel your card and order a new one.

Guess/Answer

If someone has something to tell you, and they want you to guess what it is, try not to guess it correctly. You don't win anything by doing so, and instead only deflate the person's enthusiasm for telling you what it is.
