Uh, what? Has Kevin ever done ANYTHING for a living, much less working the con circuit? What on earth would he have done at a con, tabled as an artist? I think I've seen him draw one (1) thing in the entire time he's been on the farm, and it was pretty lackluster. Say what you will about furries, but there are a lot of professional-quality artists in that fandom that I'd imagine would make the Artist Alley applications pretty competitive in any con of significant size, and if you want to make a living off of tabling cons you've gotta be GOOD, popular, and really be hitting up like 15+ conventions a year and selling well at all of them. No way Kevin hits any of those criteria.
Tabling at a con is totally different than going to a con. You're tied to that table, it's a work trip not a vacation. You've gotta be hustling, drawing in customers and striking a good balance of being friendly and personable enough to make them want to buy without encouraging them to hang out and block your table from further customers. Ideally you're also taking on-the-spot commissions and working on them at your table, and in the evenings you keep working on them in your hotel room. You don't get to go dick around and hang out and attend events and party, you're there to work hard, make money.
Tl;dr, no way fag.
Also, EXTREMELY optimistic for Bonnie to suggest the kind of people buying a tranny unicorn shirt are gonna need a size small. They should be looking into more of a Walmart selection and learning towards the XXXL end of the spectrum, lol.
