The guy that works at the stand is named Shorty. So yeah, you can't see him and never will, but he's there. Did you click on the window?
Yeah, hahahaha... Well, I figured it out on my own after a while. I just went to the stand and started touching everything there and I finally got to talk to him after touching towards the bottom of the stand. I didn't even think about the "Shorty" thing until you just mentioned it. Hahaha... Fun game, but man is it short.
