It's just an EGO thing

After leaving the Army I was working as a civilian for the Navy in the office that arranged the shipment of the household belongings of servicemen and their dependents. Got a phone call from a General. I was quite respectful and business like. Called him sir just like I did every other male caller. Using his obviously experienced "commander voice" he told me to call him General not sir. I replied: "Yes, Sir." And I continued to call him sir throughout the conversation.

People who need to hear Doctor, Senator, General may have earned the title but have rarely earned the respect.
