MajorMadMax,
Yes we are a small but efficient Navy, very adept in avoiding the only rock between Norfolk Island and South America though.
On Topic,
Before I became a Middy in the RAN, I was an Able rate technician, and became very used to calling WO's 'Sir'. Now, over 3 years since picking up my 'demotion' to Midshipman
I still find it hard to not call WO's Sir. Especially if I dont know the actual Warrant Officer, it is hard to call them Mr ???. Any other change overs (Mustangs in seppo-speak) with this problem?
