The funny thing is, I used to be a shift manager at a Taco Bell. I used to bring the controller off my MAME cabinet (it was detachable), my modified Hotrod controller, my portable NAOMI rig, my cabinet PC, and more for the Christmas party (employees and their families). I actually used a trash bin at one point (older model than the one shown above) as a surface to set one of the controller and monitor setups (yes, I made sure it was clean first.)
Don't have a pic of the trashcan setup, but here's a pic of some employees and kids playing on my Naomi rig, up where people usually order (we closed early for the party.) This was Christmas Eve 2009.
