Yesterday in Corpus Christi, Texas a contractor was changing a lock inside an ATM room when he got locked inside without his phone. So he wrote "help me" notes that he slipped through the working ATM receipt slot until someone took him seriously and called the cops. From KRISTV.com:

"We come out here, and sure enough we can hear a little voice coming from the machine. So we are thinking this is a joke. It's got to be a joke," (police officer Richard) Olden said.

It turns out it was true, and the employee said afterward he got stuck changing out an electronic lock. Later the contractor supervisor arrived, and police had to kick down a door to get the gentlemen out of the ATM room.
