Well it turns out that the time (and presumably money) spent by the Dobsonville Roodepoort Leratong and Johannesburg Taxi Association and Faraday Taxi Association on having the Bree Taxi Rank in central Joburg cleansed of evil spirits was well worth it.
The two associations were so fed up at the violent rivalry between their own members that they hired had a team of sangomas (they like to call themelves "traditional healers", but I prefer the term "witchdoctors", or better yet "charletans").
So, instead of addressing their members and adjusting their business processes to ensure that these people refrained from murdering each other in the spirit of wild-west competition, these two corporate entities decided to appeal to the magical powers of the ancestors to settle it all. But I digress.
After the cleasing ceremony on the 25th of October, the taxi rank has remained entirely free of violence! Wow! The ancestors totally did it! Their magic fixed the problem.
That was until Sunday night when in two separate incidents, three men were gunned down in what is believed to be taxi-related violence. Looks like those sangomas have their work cut out for them. Blessing one taxi tank doesn't seem to have done the trick. They'll have to bless them all, as well as every road, intersection and parking lot where taxis are likely to travel.
Good luck to them!
