Have you even gone to the office refrigerator and found your lunch missing? Who eats other peoples stuff? How do you have the time to browse the bags and then pick something you like? I actually worked with someone who did this on a regular basis and justified it by saying the people would give it to him if he asked so it wasn’t a big deal. His inflated view of self importance and the fact that he was making assumptions about his coworkers seemed to escape him. 

But never fear the lunch thief again. The Anti Theft Lunch Bag will stop all refrigerator lurkers in their tracks. It’s a regular plastic bag with green splotches printed on it so your food looks moldy and unappetizing. Unfortunately it is still in the product development stage but I think the niche market is strong.
