While I was in the FEAF shooting team we once entertained the CinC Far East Forces to luncheon at Nee Soon Range during the annual inter-services match. He wasn't the least bit bothered about eating Roti Chanai with his fingers, dunking pieces in the communal curry bowl. He declared the food served in the army mess tent was "dire". I rather suspect it was really our ice cold Tiger beer that attracted him, though.
I think the classiest food I ever ate in the Royal Air Force was when "minesweeping" the galleys of our VVIP Andovers at Northolt during after-flight servicing. The smoked salmon, caviar, vol au vents and other expensive VVIP leftovers were all "finger food".
