Let's not even talk about those guys from the North West, like @HunterNW who has to buy his biltong in Pta 
Or the Boksburg guys (can't remember who now) ...
Nvm the boerewors curtain separating JHB and Pta.
Either some people either just want to be special, or they should just get into the closets and melt away from the world.
