A not so cold fridge

This afternoon Katherine noticed that one of our fridge is no cold. Look at its temperature gage and alas! 20C ?! When we were wondering why is this, we once thought that the fridge might have been out of action. Then I suddenly noticed another shocking matter – the power point for that fridge had been turned off!! Who the hell did this!!?? Those stuff such as blood agar plates, chocolate agar plates, honey samples and other chemicals in the fridge may have been off!! Kerry was also stunned when I told her some idiots had turned the fridge off. Well, we've had some idea who may have done this though... # Fortunately I'd moved all my charcoal agar plate into another fridge before...:P
