Have you ever found out money that had been given to you was counterfeit?

No, I haven't.

When I was selling black market cigarettes on the street in the skids I acquired two counterfeit tens and a twenty.

Wait... there are actually people who will GIVE you money?  I need names!

When I worked retail, a "stoner" tried to pay with a copy of a $5 bill.
I mean, it was made on a copy machine ... and had a black & white image of the bill on one side, and blank white on the other.
And he honestly couldn't understand what was wrong with it.

LOL

Nope.



Australian banknotes are very hard to counterfeit - polymer, with a transparent window that reflects a hologram under blacklight.
