laxskygal's feelings are those expresed by the 10% or so that seem to not like the word. Thw hole "sex kitten" thing or whatever was a 70's blip, as previous to that time the words steward/stewardess were quite glamourous, and I believe still are and much more so than flight attendant.

As for server, personally I find the word so demeaning that it doesn;t even come into my mind. I know of no quality restaurant where these people refer to themselves as servers, to me it seems like a more fast food or lowend chain restaurant type term.
