Seems like there are two ways to handle a robbery. Either you do the smart thing which is to cooperate and give the robber whatever they want and let them leave or you do the "Hollywood" thing and try and be the hero by tackling the person. Apparently their is a third option, reprimand the robber enough to shame him into leaving and turning himself into the cops.
While the story makes for a good laugh, the truth is, it was probably a pretty stupid thing to do. The 59 year old female employee is probably incredibly lucky she didn't aggravate the assailant. Still, I really wish there was a YouTube video of the whole event somewhere!
