Three contractors . . . one Mchaga, another Mpare and the third Msukuma are bidding to repair the Ikulu fence. They go with a one of Ikulu official to examine the fence. The Msukuma contractor takes out a tape measure and does some measuring, then works some figures with a pencil. "Well," he says. "I figure the job will run Tshs 100,000,000 . . . 40,000,000 for materials, 40,000,000 for labour and 20,000,000 profit for me." The Pare contractor also does some measuring and figuring, then says, "I can do this job for Tshs 80,000,000 . . . 40,000,000 for materials, 30,000,000 for my crew and 10,000,000 profit for me." Mchaga " a.k.a Mangi asilia" contractor doesn't measure or figure, but leans over to the Ikulu official and whispers: "Tshs. 300,000,000." The official, incredulous, says, "You didn't even measure like the other guys! How did you come up with such a high figure?" "Easy," Mchaga contractor explains, "Tshs 100,000,000 for you, Tshs 100,000,000 for me and we hire Msukuma or Pare to do the job."
