A man walked into a Circle-K in Louisiana, 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...$15.

(Here's a conundrum. If someone points a gun at you and gives you money, is a crime committed?)
