While stationed in Singapore, around 1969 I was detailed to take part in an exercise “up country,” into Malaya. I was detailed to drive a Bedford RL 4x4 3 tonner loaded with some sort of radio equipment in convoy with another other 3 tonners and a bus loaded with the sparks radio operators, finally ending up at the Aussie RAAF station at Butterworth. We had a great time with the Aussies at night playing snooker, a few beers a good yarn, and of course a lot of good humoured banter. Brilliant.
The first morning there, one of the Aussies greeted our (very) young RAF pilot officer (the lowest RAF officer rank) in charge of us with “G'day mate.” The pilot officer declared, “Mate? I'm not your mate.” The Aussie muttered “Bloody stuck up Pommy bastard” and walked off. The pilot officer went bright red in the face, spitting and spluttering, which caused the rest of us “erks” to go into hysterics. That didn't go down too well either with our very young “Rupert” either.
