I killed the fridge. Well...actually, my colleague killed it when he hacked at the freezer compartment with a bread knife and let out all the refrigerant. So...not communal fridge and bad earth karma for releasing CFCs into the atmosphere and depleting the ozone layer (it was a very old fridge). Spoke to our resources manager about getting a new fridge. She wasn't terribly enthusiastic. Apparently it is low on the priority list.
