Hey Beags I don't understand that 20 hour dig thang either. On ships, I used to wonder if the Navigator or the Captain ever went to bed, poor buggers. Always on the bridge, I mean all the time.
My old Lt Cdr Flying used to be up in Flyco for 14 hours+..long days. For months on end.
Admit it man - service for the royals is just...mostly token. Mostly show. Its
PR and in this one, William has got it wrong.
