A lot of people leech off their own companies electric bill. That's not the way I would want to be running my rigs, and that's why I chose not to invest into GPU mining. I know a lot of people don't care and just do it anyway, but that would bother me if I didn't pay for the electric.
Are you talking about me? It is my dads company and the power to the rig is metered. I will be paying the bill.
