Many years ago, I worked in rather a crazy place: CP Air Lines flight kitchen. Chef de Cuisine was former SS, had made dinner for Adolf in 1938, Sous-chef was Dutch and hated anything German, Second Cook was Austrian and hated "the Nazis" (he was former HJ but didn't mention it), things like that. My direct boss was Irish, sailed with the Merchant Marine on convoys for 6 years, most of the female help was Russian or Ukrainian, Commissary chief was a Dutch collaborator, Department head was an American draft-dodger, Janitor was a Pole who had been a prisoner of the Germans AND the Russians, escaped to France, then to England, Polish Arty up through Italy. The Polish janitor, the SS Oberscharfuhrer and the Irish sailor were the only ones with actual COMBAT experience .... and they ate lunch together. For them, the war was over and they could be human beings again. Everyone else still was busy hating but we all worked together okay.
But the Butcher was SWISS and his war experience may NOT be summarised in family-grade language. Nicest thing he said about it was, "SIX YEARS I am up in those stinking mountains, FREEZING MY A$$ off...... VAITING to be invaded...... AND NOBODY CAME!!!"
