A quick-change artist recently duped a clerk in Roseville with an old scam.
On March 1, a man gave the clerk at a Harding Boulevard business five $20 bills and requested a $100 bill in exchange.
The clerk handed him a $100 bill, but the man showed her a $10 bill, claiming that is what she mistakenly gave him, according to a Roseville police activity log.
He eventually talked her into taking back the ten and giving him another $100 bill. It's an old trick, police said.
