incentives always work better than sticks, esp when your sticks are silly. Like anyone is really EVER going to stop someone form removing their own machine from any show at any time.
Good way to sink a show completely if you start having some beefy security roidboy yelling at people that they cant remove machines; machines they own and brought to your show so you could then make money off the show. LOL, what the hell is it with some show organizers...
