I flew with one of those just the other day. I kinda made a joke out of it and called him "Captain Micro" a few times. When he asked why I called him that I told him it was because he micro manages too much. I don't fly like him so either fly the legs or let me fly. I'm not just some voice activated autopilot system. The rest of the 4 day anytime he'd start micromanaging I'd just call him captain micro and he'd back off. He'd say something like "well I don't really care but there are other captains who do and they'll snap at you". I wouldn't respond back to that but in the back of my mind I'd be thinking that if there is I sure haven't met him or anyone close.

Ever notice how a CA always uses the "To me it's no big deal... but.."

For your situation I advise to call him Capt. Micro, avoid his employee number, or simply say that you aren't challenging his authority you're flying the plane how you'd like to and unless he can show you where you're doing something wrong then you'll keep doing it. Tell him he's f'ing with your mojo and making you fly like crap because you're having to focus on him more than the aircraft and the situation at hand.\

Then wait till he's making a bad landing and ask the tower for lower lol.
