When not reading the manual really did cost money

According to an article in the Virginian Pilot, a local man was able to reprogramme an ATM to give out $20 notes instead of $5.

What the article didn't reveal was that it's suspected that he did it by reading the operator manual for this machine. Unfortunately, the original installation engineer probably didn't read the manual, because he/she probably omitted to change the default access codes for switching the machine into diagnostic mode. This is a case, perhaps, where the manuals shouldn't be published on the Web!

According to eweek, it continued to dispense more money than it should have for nine days, until some honest individual pointed out the problem.

There's even a video of alleged thief in action. If you recognise him, do let the Virginian State Troopers know!
