When I was doing my OE as a new guy on the ER, I got sidestepped on final on an approach into LAS. I immediately went head down to reprogram the FMS when my LCA said, "You're a Herc guy, right? Why not just turn all that crap off and fly the plane?"
And - boom - there I was, right in my comfort zone. "Turn all that crap off and fly the plane" is probably the best advice I've ever gotten as an airline pilot. Well, that and "Never drink with the FAs."
