I was bemused by the senior crew member on a recent MAN-LHR flight deciding to get out of his seat while we were incoming, still on the active runway. A folder had fallen off the counter in the galley, and once the major deceleration had stopped, but before the turn off the runway, he obviously decided it was a good time to do his filing.

I would have taken a picture but my camera is electronics, and turning that off will cause the plane to explode
