People who hide their PIN

You do realize that I would have to attack you on the street to steal your debit card in order to rob you in knowing your PIN, right? I would have to leave work at the moment you leave, chase you down in broad daylight, attack you and go through your stuff to find your debit card.

And I thought I was paranoid.
