Do me a favor ... Could say senator instead of Ma'am. It's just a thing, I worked so hard to get that title, so I'd appreciate it, thank you.
The video clip is here.
I've had the same thing happen to me when I worked for a defense contractor.
"A point of personal perogative, Mr. Hankamer, but my title is Dr. A__."
This from a Government lab manager during a briefing (and never mind the fact that he knew from my business card that I also have an earned PhD).
In Sen. Boxer's case, it's not just the generic snottiness of (many of) our government employees - it's the abysmal ignorance of standard military protocol (from a United States Senator, for God's sake) and the complete lack of common courtesy.
The hostility of the Left to the military is palpable.
