Ditzy, my apologies, I'm not trying to imply that you are rude or anything like it.
My point is that the person in question was in all probability thinking she was showing an interest in you. I don't believe she was trying to be personal or offend you. Some people are like that! Then again, women can be so bitchy sometimes, you can never tell!!
(That was tongue firmly in cheek by the way!)
Of course, there is no justification for being rude or impolite to CC, e.g. telling you that you should get your teeth done for goodness sake! Were they American by any chance? As SLF I never am rude and I don't make comments either. As I once told my wife, who I was gently scolding for beliving you guys are just there to serve drinks, I am polite to you because a) it costs nothing to be nice and b) I never know when one of you will be shoving my backside down an escape slide. (Never hopefully!)
