"SASless, in the RAF it is often the 'commissioned ex-rankers' rather than the straight-through baby officers who make the most smoke and noise about their new-found status in life. Real officers treat RAF WOs with the respect their status rightly merits."

In my experience that is arse. As a "hairy it took me about 2 years to stop calling WOs sir when in uniform, and I had been a member of Sgts mess so had a bit of time to get used to the first name terms.
However, it does take the green shielders less time, because they usually drop their first bollock within a minute of meeting a WO on station. At this point their ears get pinned so far back that they cannot keep stop their SD hat sliding down to their nose.
