^I'm not sure that qualifies him as an asshole, maybe more someone who's just trying to make a living going to these conventions and isn't really as in to it as other people might be (for example, anime voice actors etc. LOVE conventions because it's where they get the most recognition.) He's always seemed like a generally nice guy. His parts were relatively minor, and he's had other things to do with his life - so I certainly can't blame him for forgetting the no-doubt minuscule details people were asking about at the convention.

Now if it turns out the questions weren't really obscure nerdy trivia and would have been simple to answer I would retract a fair amount of the above, but I've never heard anything about him being an asshole before.
