Excellent news story on an undercover Domme from here:

A thief who hit a Subway sandwich shop in Houston, Texas got more than he bargained for. When he reached over the counter and grabbed some bills from the open cash drawer, the gal behind the counter hit him. The shocked robber fell back against a wall, but then realized he had the money in his hands and made a run for the door. The young lady jumped over the counter and then jumped on him. She shouted to the customers standing around to give her something. Someone handed her a pair of handcuffs and she cuffed him. Then someone else handed her a Taser and she zapped him with it. That kept him quiet until the police arrived and arrested the thief. What are the odds that someone enjoying a sub would be carrying a set of handcuffs?
