Bribery in all its forms - petty, blatant, subtle, systematic or institutionalized - is pretty much a way of life in South Africa. Of course you get the whites who say it's an African thing, but in reality, is a human thing, borne out of economic desperation, bureaucratic frustration and maybe even civic creativity.
But knowing all of the above still didn't inoculate me from the stupefaction of being hit for a bribe by the immigration supervisor on duty at the airport when I left for Manila during the Christmas holidays.
