The CA didn't have to give him the jumpseat. That means the captain is actually the idiot in that story for not acting within his command to resolve the issue before leaving the gate. And if he did react as stated (doubtful) he would be summarily terminated without union representaion (Rule 32). A good CA realizes that an FO can make a big difference in his quality of life and that it's not a good idea to burn bridges. Aviation is a very small world.
