Yes Beagle, I spent my KD allowance on KD, however, as I had several 'KD wearing posts' one after the other, I quickly found that I needed to dip into my own pocket. I made a mistake of buying some KD in UK before my first trip and arriving in it. At HQFEAF, I was introduced to a charming (much older WRAF) officer, who was told to take me to Changi Village and get some real stuff sorted. In my third jaunt I acquired a No: 6 - the smartest piece of kit the RAF ever had IMHO. The downside was that I was then promptly appointed O i/c the station Guard of Honour.
Being of 'modest stature - alright, I'm a shortarse' - I was given my jungle greens by a friendly Ghurkha officer (2nd/7th GR in those days) and for many years, all my RAF kit came from Au Wai Lam, the station tailor at Kai Tak. My big regret was that I never got a 'genuine' Bates SD hat.
