Turns out one of the guys actually lived there. He cooperated with police and ratted on his accomplice.
I talked to the driver yesterday. He\'s back at work, though he said the hit the guy gave him on the side of the head (behind the ear) almost knocked him out.
Our store is in a pretty good area except when we have to go "down south" which is pretty ghetto. So far, just two robberies when dumbass drivers didn\'t lock their doors in a bad area, and one car theft (found later that day in a ratty neighborhood).
