I know this is late, but I was wondering who he was? Seriously, if anyone knows tell him thanks from me and about everyone for making the con so much fun, and making everyone so much happy. He was the unsung hero this con!
Their phone # is on the bottom of that page, I'm sure if you called and said something along the lines of "tell your staffer from nekocon, the one who was selling pocky to people waiting on line, that we really appreciated it!" they'll get the message to the right person. It would prolly encourage them to do the same at other cons too. I keep looking for him when I go to the store, but no luck yet. That, and ironically, they're really low on pocky right now!
