Louisiana - There is one bandit in Louisiana who had better give up armed robbery until he learns how to count. The man walked into a small store, put a $20 bill on the counter and asked for change. When the clerk opened the cash drawer, the man pulled a gun and asked for all the cash in the register, which the clerk promptly provided. The man took the cash from the clerk and fled, leaving the $20 bill on the counter.

The total amount of cash he got from the drawer was $15.
