Looks like it definitely varied by person and who was doing the counting... I ditched all my obsolete holos, obsolete rares, and obsolete non-trainer reverse holos there, none of which had been pre-counted to be visible (I knew the count, just hadn't separated them into piles), and if you stick to the per card prices that are back on page 2 of this thread (page 1?), I should have gotten $214 exclusive of the Pokemon-ex (again, all obsolete) that I had. The guy there offered me $325.
I do agree that for the 2 minutes I was at the booth, the guy did seem rather... I dunno, uptight? Just the way the one end of the booth was all stacked up, they certainly did seem completely unprepared for what was coming.
