Vent:: I didn't ask for commentary

WHOA. You're far more forebearing than I am. I would have given him benefit of the doubt for one comment, but then I would have been just a wee bit confrontive. Something along the lines of, "I'm quite sure you are not employed here to comment on clients' bodies or to give medical advice. So give me a knife NOW." 

Or I might have just asked for the boss and filed my grievance right in front of the ********narl*

You're way too polite, haha. I like "mind your own ******g business" but that "Am I speaking Swahili" comment is usually my second choice. ;)

This is where the teacher look with the raised eyebrows and the hand outstretched does wonders. Sometimes a look is more effective than a word!!! Then there's the baseball bat technique...
