Convention runners should be picky about who they have at conventions, I’ve seen tons of scratchers in the past. Honestly this story doesn’t surprise me at all unfortunately. If you have any friends in the area you’re going to, you can usually put a request in your application to be next to a specific booth, but it’s not always possible.

I say educate any and every chance you get. But approach them and say look what I’m about to say is because I care about you and all involved. But usually from what I have seen they go back to it just like a preacher giving a sermon on Sunday it usually takes the worst case scenario happening before they will change.

Can you report him to whomever sets up the conventions?

Rent a whole booth Easy peasy
