You can often politely dodge probing questions about your employment. When someone, for the purpose of small talk, asks me what I do for a living I just say I'm an exotic dancer or a runway model. It's funny and breaks the ice a little. Then I'll ask them about their watch or something. If they insist "no, really, what do you do for a living??" I'll politely say I work with computers and again try to move on. Very rarely I'll get someone who won't drop it "come on, WHAT COMPANY???" and at that point I know they're really not interested in talking--they just want to stack rank me in terms of importance or salary or whatever and I politely dip.
