According to local reports,
"We never thought we'd get robbed because there's always so many people in here," Nickel said. "We were in the back mixing some boudin and everybody came in and goes: 'Run, run outside. There's somebody in here with a gun.'
"I looked out a window and all I could see was his hand with a pistol. I didn't know what to do."
That's when Nickel took action. He fired two shots, hitting the man in the back of the head.
"Just spur of the moment," he said. "I just did what I had to do. Everything happened and I just did it on instinct. I was just worried about everyone else in here."
Unarmed, the store manager would have been left with the choice of potentially watching an employee killed of of fleeing and abandoning a teenager held at gunpoint.
Just another good guy with a gun that gun grabbers don't want to talk about.
