A collegue at work has a brother serving in the RAF at an undisclosed RAF station in the North East of Scotland (thats going to be hard to work out). There was a thread going on Facebook about Costa coffee and somehow my mates brother managed to slip in that there was more to life than worrying about the price of a Costa, especially when he is about to go "in the field" and be shot at. I politely said "RAF? Field? Your having a laugh!" He got a bit uppity about that and said "Yeah. As force protection we do actually live in field conditions". Turns out he is off to Afghanistan after Xmas. Sooo..I mentioned that I have been stationed at the same airfield with the resident RAF Regt and the Reserve unit there, had been Force Protection and had volunteered as part of a MERT team and came out with a few "insider" jokes. He went quiet. I asked my mate if I had offended his brother by calling him a car park attendent etc. He looked confused. I asked him what his brother did...turns out he is a flight planner and works in the Control Tower! Jeeeeez!!
