Re: The cleaner did it.
Told to me by an oil company friend:
"We were posted to Egypt. While we were away a contractor came into our flat to do some work. They unplugged the freezer (full of meat) to use the socket for their drill and forgot to plug the freezer back in when they left. When we came back a week later we didn't even try and clean the freezer but had the whole thing with its putrid contents taken to the tip."
