I have been flying with such people with irritating habits (doing the things already mentioned) ever since I started mutli-crew flying.
I am also trying to work how to best deal with them and the moment I just suffer in silence.
Unfortunately some of these Captains think they are so good, think they they know it all and think they are always right. I fear if I say something to them, it will have an opposite effect and make them even more irritating to fly with.
For example, they might see me as challenging them. Then they will continue to reinforce their irriating habits and introduce more to show that they will never give in you as they are always right and you are always wrong. They are the boss and they want to know about it. They will continue to fly the way they want and never give in to anyone. You question or challenge them and they will further reinforce there authority to do such irritating things in the flightdeck.
I have seen other pilots have full on arguments and shouting matches, which probably started off by the fact that one pilot was irritated by the habits off another.
Sometimes it easier to suffer in silence I think and keep the peace, even though it may be very painful.
