A Useful ATM Tip

I heard a really useful tidbit today about safety measures at ATMs. If you're held up at an ATM by some robber, and they want you to withdraw money for them, type into your PIN number backwards when you enter it. This alerts the bank that you're in trouble, and I guess in effect they notify the cops. I remember hearing this a long time ago, but I have forgotten about it until I heard it again today. Hopefully, you'll never get robbed at an ATM, but if you ever do, you now know what to do. So stay safe!
