Chevvron RAF Standard that was.Same at Sopley (Southern Radar) in the 1960s; the last duty of the night ATCA was to chuck packet of tea, packet of sugar, tin of condensed milk, water into the urn and boil it all up. At intervals through the day the process was repeated as required, First duty if the night ATCA was to empty the urn which by then had a layer of sodden tea leaves several inches thick at the bottom. Needless to say the inside of the urn, and of the tea mugs (mainly 1 pinters nicked from transport cafes) was a rich mahogany brown,As civvies we were exempt from what little bull there was (anybody remember the LS WAAFs and the Teddybear Club?
) however we were required to make an effort for AOCs (?) inspections. This involved a tin of Vim and a scrubbing brush being used on everything in sight. I quickly learned to hide ny own mug but iIt normally took several weeks to get the brew back to an acceptable taste
