Three contractors are bidding to fix a broken fence at the National Library. One is from Cape Town, another is from Durban and the third is from Gauteng. All three go with an official to examine the fence. The Cape Town contractor takes out a tape measure and does some measuring, then works out some figures with a pencil. "Well," he says, "I figure the job will run about R19 000. R9 000 for materials, R9 000 for my crew and R1 000 profit for me." The Gauteng contractor also does some measuring and figuring, then says, "I can do this job for R17 000. R8 000 for materials, R8 000 for my crew, and R1 000 profit for me." The Durban contractor doesn't measure or calculate, but leans over to the official and whispers, "R37 000." The official, incredulous, says, "You didn't even measure like the other guys! How did you come up with such a high figure?" The Durban contractor whispers, "R10 000 for me, R10 000 for you, and we hire the guy from Gauteng to fix the fence." "Done!" replies the official.
