There was one 757 Cap I had at recurrent in about 1990 who'd just come off 25 years on the 727, who didn't like to "push buttons" on the FMS. So I did as much of that as the IP would allow but finally I got a tap on the shoulder from the IP who mouthed the words, "Let him do it." So I had to watch as he struggled but he got it done.

And to keep it even, I once had a 777 FO at recurrent who was so worthless the IP nearly busted him in the oral! He didn't know about half of the walk around slides! YGTBSM! Then when we got into the box I was pretty much single pilot. I was dismissed from the debriefing....never saw him again.
