What are worse are those damn "vanity fridges."
We had one of these at the office that we received from a sponsor. The thing ran 24x7, and it was very loud. We still had a "real" fridge, so this thing ran continuously (with the lights and everything) with one bottle of soda in it, until I finally unplugged it. Somebody kept plugging it back in, but after two or three days of me unplugging it every time I saw it, they gave up and left it unplugged.
I wish I had put it on the Kill-A-Watt to see how much these things waste (and they're in every grocery store and gas station.)
