OTG...I'm with you.
I too chose to be involved, and fortunately, TWA was a true Captain's airline, so those of us who thought that our area of responsibility extended past the cockpit door knew we would be supported as long as we were right.
It wasn't often, but there were times when a Captain's presence was all that was needed to get things back on track. What was not needed was the guy who got on board, plopped himself down into the left seat, and told the FAs to handle things. These people weren't Captains...they were glorified FOs.
