A man in Texas was trapped inside an ATM for hours. He was changing the locks on the tiny room that leads to the ATM from inside the bank when the door swung shut locking him inside. Since he left his cellphone inside his truck, he had no way of calling for help.
He used a pretty innovative way of finding help. He passed handwritten notes to customers using the ATM asking them to call his boss to rescue him.
He passed these notes to multiple customers before one finally called for help and had him rescued.
