Recently I had a fallout with a close colleague of mine at work that sort of escalated into a grave situation. In retaliation (which is pretty minor compared to what he did), I took his cigarette lighter and hid it from him. We've been telling him to quit smoking anyway. He threw a fit upon discovering his lighter was gone. To spite him further, I plan to put his lighter in the fridge in the office pantry. He would find it there himself. My question is, would this have any effect on the lighter in the fridge? Frozen and unusable thereafter? Or should I think of another 'harmless' plan?
