At some point during my teenage years, my dad gave me the one of the most useful pieces of advice I've ever gotten: "the world is full of assholes, don't let 'em get you down, but don't put up with 'em, either."

Or, in this case, don't work with them, or recommend that anyone you know work with them, because while the world is indeed full of assholes, it's also full of enough awesome people that you should never have to put up with the assholes.
