Employees of convenience stores and fast food joints continue to fight back. Late Friday, a convenience store clerk in Gastonia hit a robber in the head with an aluminum baseball bat. "I knew I had to take care of the business. This is like my home," Guillermo Troncoso told the Charlotte Observer. He also busted car windows as the robber was driving away. Gastonia Police arrested 47-year-old Randall Scott Strait on Saturday. They saw the busted windows of his Mercury Cougar outside his home, and then found him inside asleep with a bandage on his head. This makes at least the fourth case in the last year of employees fighting off would-be robbers in the Charlotte area. Last month, a Subway employee in north Charlotte shot and killed one robber, and wounded another. In October, a Pizza Hut employee in East Charlotte shot and killed two robbers. And last summer, two clerks at a Food Mart in Union County shot and killed a robber.
