Navy chefs were good lads (and good women).
Always put a "night flyers" meal on for us onboard the CVS. Hot meal, sometimes the leftovers from the main meal, but sometimes pie chips and beans. Or similar. But hot. Then a cup of tea, fag or small cigar in my case, back to work......not rocket science.
But always appreciated by me.
Is it true hundreds of RAF groundcrew died in WW2 from illness brought about by working generally at night in Winter on aircraft out in the sticks in the airbases of Bomber Command?
Lot to relearn, every generation finds this.
