ATM Repairman Accused of Taking (and Faking) Cash
fysdt writes "An ATM repairman was nabbed in Phoenix on charges of having stolen about $200,000 in ATM funds. His method was almost brilliant in its sheer stupidity: He pocketed the cash, and replaced it in the machines with 'counterfeit or photocopied $20 bills.'"
To be fair, he was a Diebold employee. He probably assumed that there was no fraud sufficiently blatant to be punished for.
More realistically, he was probably an opportunist, possibly with a newfound need for fast cash, and good counterfeit currency, while certainly not impossible to make or obtain, is not something you can just get ahold of in a moment. Were a sophisticated counterfeiting operation looking for a dispersal method, an ATM service dude might be a useful 'hire'. A random ATM service dude probably doesn't know how to just look up the local counterfeiters...
