I think i'll tell him.
My company just hired this black guy because we are about to bid on a government contract. We're a construction company. He'll be a flag waver or something. The problem is that this guy wants to hang with us after work. We usually get a few beers. Nobody wants him around after work. Two of our group are females. We just don't want him drinking and talking to them, ok? This, to us, is very understandable. He seems like a kind of nice guy, but come on. I think I'm going to tell him that one of the women has a problem with black dudes. That's the kind of lie that he'll believe and not question. In fact, it sounds pretty normal huh?
