Totally agree Schneider,
The headset should NOT be worn and as for the shoulder straps, are they expecting to HIT SOMETHING while I'm out of the cockpit?
As far as the other chap was concerned, as I said, if he was that tired, he shouldn't have been at work in the first place. And you don't just nod off curled up in your seat, that's deliberate.
Controlled rest is just that; controlled. Controlled by discussing it with the other pilot, etc.
