i work with a diverse group.. of course we all do. a few of them are 'african americans'. and a few are real africans. those from africa are a lovely group.. hard working, polite and have a great sense of humour. they are nothing like their "african-american" cousins. in fact they are insulted by the black americans. real africans work hard, have an ethical work habit, but "african americans" just look for excuses not to work and reasons to make sure that if they arent performing up to par its because their bosses are racists.
just my observation
