Nope. I physically couldn't have brought myself to salute Bliar, Hoon, Blunkett, Mandelson, Reid or any of the other worst offenders, regardless of b0llockings or disciplinary action. As for "Sir" the only recipients are more senior military officers and the Royal Family. Post-titles for everything else!
I saluted an Army major once. He was without hat. He stood to attention as I passed to return the compliment. A gentleman!
