When I worked at EA, someone brought his own coffee maker to their cubicle because he liked brewing his own and having it just they way he liked it. No one had any problems with this as far as red tape or corporate policy goes. However... we were a bunch of game developers. So everyone had a high-powered Windows PC and one or two console dev kits in their cube. The PS3s were so notoriously power hungry that in summer months people would run box fans to try to blow off some of the waste heat. Each circuit in that poor building was heavily loaded. The coffee maker had to go once someone finally realized that turning it on was the straw that broke the camel's back and caused the circuit for that row of cubes to trip and everyone's UPS to kick in.
