As a fairly senior bod I will admit that I will salute any lady i recognise - including SAC Snook's wife. I will salute any officer in his office if I have my hat with me - normally beginning and end of day. In defence of THS I will normally remove my hat entering a building but replace if entering an officer's office (see previous). Colours, coffins, quarter-deck, royals, senior officers all get a salute. Thankfully, I return more than I receive (no pun) but I see it as a privilege and do not begrudge those seconds of exerting my right arm. And finally, the PM or any other poli or senior civil servant - not in 31 years and hoping not to whilst still in uniform.
