Ali Mwaura, aka Biggie, runs a wholesale shop in an estate in Nairobi. He redesigned his shop to ensure there was only one inlet to the premise, and one door to his back stores. He then installed a paying counter half way across the shop, which gave him a good view of customers getting into his shop. His lofty position allowed him to watch his staffers carry merchandise from the store, and out into waiting vans.
