"The left hand side refrigerator has apparently come to life and decided that it no longer wants to keep your lunches cold. Thanks to Skynet, it has switched itself to defrost mode as part of a larger plan to eliminate humanity through the allowance of salmonella growth. If you have your lunch in it, you may want to move it to the obedient, non-sentient unit on the right. You may want to keep an eye on the microwave while you are in there."
