During the sweltering summer of '76 I was based at Bawtry. The AOC gave permission for dress rules to be relaxed and we were allowed to discard ties and roll up our shirt sleeves. One day I had to travel across to Finningley for some admin matter and on checking in at the guardroom I was approached by the SWO who took exception to my appearance. When I explained the AOC 1 Group's missive he reminded me in no uncertain terms that Finningley was not part of No.1 Group and I was sent packing to the mess to scrounge a tie before the CO spotted me.
