Brain goo probably stains terribly.
He should have pistol whipped the robber!
I applaud his restraint, but I'm guessing if that guy had made even the tiniest move to bring that gun back up, things would have turned out very differently.
My only issue with NOT firing, is now bad guy knows clerk is armed and maybe next time doesn't hesistate to draw / fire upon entering to get the drop on him?
Guy was awfull slow and Nonchalant about pulling is gun to rob the clerk. Good for the clerk. Good guy wins again.
