Blacks often don't tip well or at all b/c it is VOLUNTARY, so why give money to whitey (often with an attitude) when whitey is the adversary. Seems VERY logical to me. The fact that white customers VOLUNTARILY tip blacks servers is consistent with the fact the whitey is SCARED to not tip--smart move unless they want that "extra" sauce on that burger...btw, XXXtra sauce blends in nicely with all that mayo whitey likes. So in the end, both groups behave logically and selfishly, but from different perspectives. Thread dead NOW.
