re: A gal in front of me just tried to pass an obviously counterfeit bill

I drive around with fake 20s and 100s to impress people all the time.

Obviously an amateur. The idea is to pass them in transactions that require 3 or 4 $20 bills and you pass them off 1 at a time. So 3 real 20s and 1 fake.

A Secret Service Agent had told me how the counterfeit dollars can get in to the money stream.....even with those pens. If the paper is high enough quality the pen at the register is worthless. The banks however can pick them up.
