Local Dollar General store manager did Crocodile Dundee to a wanna-be knife-wielding bandit. MJM congratulates the manager for his cool. It is good that the bandit did not have a gun; good that he ran.
Main point: Anyone, anytime, anywhere. This is not the first time for this store. Thieves think they can threaten banks and store managers with an index finger in a pocket, and run with the money. Mostly, they can. Immediate repercussions do not strike them as great. Two to the chest would have sent a powerful message. But, the civil and even criminal liability potential both dissuade good citizens from self-defense.
