If you're working in a cube farm or anywhere where an office fridge is used by several people you probably know the problem. Not only is forgotten food rotting in the fridge giving off all kinds of odors.
Judging by the numerous threats and passive-aggressive notes left because of it I'd say it is also very likely that one of your co-workers will help themselves to your lunch eventually. If that was intentional or not we will never know but here's a neat idea to prevent it from happening again in the future.
The Anti-theft lunch bag. Its mouldy green spots make it look absolutely disgusting and you're left hoping that your co-workers won't bin the offending sandwich because they think it's actually way past its use by date. Should that be the case I would defend the "If I can't have it noone can" strategy.
