I did virtually join a few years ago when I worked for a large contractor in a Norfolk base. I'd left the Raf in 99 and started working in the same location as the RAF approx 10 years later, kidding myself that it would be something akin to really good...I couldn't even speak the same language.
The jargon was completely different to that which I'd left and 99% god-damned american phraseology ruled.
I bit my tongue quite a lot and managed to last 4 years - but that was more than enough to remind me why I left in the 1st place!
