A man made counter fit money and accidentally he made a $15 bill.
Crazy enough to believe that he can use it. For that he drove to countryside and saw a convenient store. He went inside the store and saw a funny looking man behind the counter and he believed that he will use his $15 bill here.
He walked to the cashier and asked him if he can have a change for $15.
The cashier told him that he will give $14 for change. Man was very happy for getting $14 for a useless bill, so he agreed for that and said OK.
Cashier opened his cash register and gave him 2 $7 bills.
I am empowered with what makes sense!!!
