Yeah, I mean there are questions and then there's wasting time. Sometimes a seller might be totally wrong about which is which; that definitely happens. But if I'm a buyer and I need to ask something, I try to be really succinct and also make it clear why I'm asking. (Usually it comes down to contradictory descriptions that I just want clarification on.)
One thing you have to remember about sellers is that they still own the item being sold. And you don't know why they're selling it or how motivated they really are. I've put stuff up on Ebay that I either just wanted to get rid of, or alternately, that I didn't *really* need to sell at all but was just testing the waters on for what I thought was a crazy price. In both of those cases, I don't really want to answer a bunch of questions. I will, but that's because I'm a decent person. But I don't want to. Somebody else who has less respect for social niceties probably wouldn't, or would but would do a bad job of it.
Honestly, though, if somebody asked me where I got an item from... unless I could think of a reason why that would be relevant, I probably just wouldn't answer. It's my thing, what business is it of yours where I got it? You don't walk into a grocery store and ask them where they got the Rice-a-Roni they have on sale. That's what I was talking about above. If it's a rare promo item or something, or a prototype Atari 2700, then ok, maybe I'll answer. But for most items, I think that question's a little unnecessarily personal.
