If you should ever be forced by a robber

(GOOD TO KNOW) If you should ever be forced by a robber to withdraw
money
from an ATM machine, you can notify the police by entering your Pin #
in
reverse. For example if your pin number is 1234 then you would put in
4321.
The ATM recognizes that your pin number is backwards from the ATM card
you
placed in the machine. The machine will still give you the money you
requested, but unknown to The robber, the police will be immediately
dispatched to help you. This information was recently broadcasted on TV
and
it states that it is seldom used because people don't know it exists.
Please pass this along to everyone possible
