This reminds me of a funny conversation I had once with a recruiter. He essentially demanded I provide him a salary number to give to a prospective company, as I had been flatly refusing to on the basis that it puts me at a disadvantage.
Eventually I threw out the highest amount I'd ever earned, about $225k a year total comp (partly tongue-in-cheek, partly to make a point), and he got really angry with me, telling me I was wasting his time and that nobody got paid that much. Needless to say, I ended any dealings with him at that point forward.
