That Trick Won’t Work Here
This guy came in my store, and without even glancing at any merchandise, comes to the register. He hands me five $20 bills and asks for one $100 bill. As unusual as it was, I obliged. After I verified all his $20 bills were legit, I pulled a single $100 bill from my till. This is the part that saved me—I held the $100 bill up to the light just like we were trained to do every time we handle a $100 bill. Only $100 bills and not any other denomination.
He took the $100 in one hand, turned away from me, turned back and showed me a $10 bill, and claimed he was short $90. Without even thinking, I pointed to the door and told him he could leave or I would be calling the cops. He conceded and left without another word, shame-faced.
The thing that saved me is that $100 bills are the only ones we look through at a light. The cameras saw me do that and I knew I had him dead to rights.
