Bingo.

WTF do these assholes expect? That they can wear pajamas and slippers, while swearing and smoking a cigarette at work? And that goes for ALL races. They're paying you to represent the company professionally and if your social circle is radically different than your professional circle, then you better be able to flip the switch.

And maybe instead of blaming "the white professional world" they should blame black culture for ill preparing them for the professional work place.
