Col or Lt Col it matters not as in the socialarea they are all Colonel. A few Sirs dropped in to the conversation would not go amiss.
Now a flt lt I know really endeared himself to his CoC. He called the major by his first name and flattly refused to call the Lt Col - Colonel Bob (or whatever) prefering instead to call him Boss.
Funnily enough our tree surgeon called me Boss but his sidekick said it didn't seem right and called me Mr PN instead.
