Green Market Square

In the centre of Cape Town there is Green Market square: a very touristic and very lively arts and crafts market. It's a great place to sit outside a Cafe and have breakfast whilst watching people go about their business.
There is a guy who walks around Green Market square. The first time I saw him, I though he was a security guard. He had one of those "stun guns" for security guards which deliver an electric shock.

I watched him walk around the square. Then without warning he takes out his stun gun, walks up to a guy and zaps him. The guy jumps, looks a little shocked and then walks on. The guy with the stun gun then continued to walk around and occasionally walked up to someone and zapped them. He would generally chose people who were walking around trying to sell little toys or souvenirs, people begging and the occasional prostitute who wandered through.

What an idiot.

Maybe he is some kind of jobless security guard who occasionally just gets the urge to "clean up the riff-raff" at Green Market Square. I haven't seen him recently. Maybe he zapped the wrong guy...
