Don't let yourself be a victim!
A video has gone viral showing how easy it can be for a con artist to trick a cashier, and get more money out of them than they thought.
Rick Lax, a magician, says it's all about misdirection and the slight of hand.
"Do NOT try this yourself!" he writes on Facebook. "Because it is ILLEGAL and I did this for educational purposs and gave all the money back to her (and some on top of that.)"
"This scam is called "CHANGE RAISING" and it's WAY more common than you think!" he says.
