Would you like an official value added tax receipt with that 40inch TV? No problem, that will only cost you an extra $42.
We watched a woman in downtown Nairobi in this very situation. She left with the TV, but without the receipt. Would you choose differently?
But do you know how much money the government loses each time you buy goods from vendors who don't issue you with VAT/ETR receipts?
Do you understand that by doing this you are actually helping these businessmen evade taxes, and deny the government much
seded revenue to provide free primary education; fund hospitals; build roads etc?
