Be sure to take your receipt. Don't leave it behind. It lists your account number and often, the remaining balance. If your ATM card is lost or stolen, report it to your bank immediately. When using an ATM after business hours or after dark be on your guard.
Chances are there is another nearby.
Have your paperwork and money ready before you enter the machine. This will not only reduce the time you must spend in the ATM but will allow you to pay more attention to your surroundings. Do not walk out counting your money.
