Watch them wallets -- they could be full of funny money.
Merchants in downtown Petaluma have been asked to scrutinize the paper money passing through their fingers after a movie theater reported receiving two counterfeit $100 bills, according to the Santa Rosa Press Democrat.
These bills are particularly tricky because they pass the "pen test" when marked with a counterfeit money-detecting pen because they are legitimate smaller bills bleached and reprinted to be Benjamins.
The counterfeiters' goal is to buy a cheap item using the fake bills in order to receive a pile of real money as change, the newspaper reported.
Merchants receiving C-notes are asked to inspect them carefully before making change. As usual, it's all about those Benjamins.
