Lunch?
In the increasing earnest 1990s, several Messes in which this civilian lived were nearly deserted at lunch time, because more and more people [blunties if you like] "worked through". Afternoon tea was often the first meal since 0700, and very good too. A lot of people ate 0700, 1630 something on toast and a fancy cake, and dinner as late as possible. That way people could be working 0800 to 1600, and 1730 to 1930, which latter period was mercifully untroubled by silly interruptions.
Seen from the other end of the telescope in my youth, the aroma coming from the aircrew feeder as I walked through the dusk to brief the 1000 bomber raids was very very appetising ...... I would have been on shift for about 7 hours on a "snap tin" and coffee/ tea.
Now I have made myself hungry. Steak, chips, onions, peas and a pint of best bitter please.
