The Dave and Busters in Michigan has an Ultracade machine there. I "accidently" spilled my beer on it on my way to play Battletech (but now I miss the beer). 
(damn im lame) 
EDIT: oh and by the way I have yet to see anyone play the machine when I am there.
Seriously, you guys aren't getting that someone who at least has an interest in video games being around for a bit (the operator) put his hard earned money into purchasing that game. Now, just because the guy made a bad choice back THEN in light of what Foley is doing NOW doesn't make it the operator's fault, and if anything, paints the people who would do physical harm to the machine as brain dead.
Sorry for the harsh words, but it's not being grasped that when you see an Ultracade out and about,
Foley has already gotten PAID for that machine!You're no more hurting him than if you walked through the parking lot at the mall and keyed every Ford because you don't agree with them using plastic gas caps!

Post the sign on the machine, speak to the op, take whatever civilized means you feel are necessary, but STOP telling everyone that you have/want to/will destroy the machine!
Use your flippin' HEADS! Let's say you had a party, everyone's playing your cabs, and you head upstairs to take care of something. You come back down, and someone's shattered the glass/plexi or poured a beer on your cab, rendering it useless. I bet you're glad they chose to demonstrate their protest to the manufacturer of your cab on the machine you spent your money on, hey?
I understand the joking nature of the posts, heck, mebbe I've even done it myself a time or two, but it doesn't help our cause AT ALL if someone maybe agrees with us, points a few people here who may not know, but wish to help, and they see crap like this!
In dealing with Ultracade and everything that IS Mr. Foley, it's the ONE area that SHOULD NOT joke around about solutions to making our feelings of him and his products known in an effort to slow/kill/shut down his business.
