Anti-theft lunch bags

I found this clever, funny and gross at the same time.

Keep your lunch inside one of these plastic bags, and it will deter your hungry co-workers from stealing your lunch. But I'm guessing it won't help raise your popularity when they see you taking it to your desk to eat. 

They are currently £6 for 25 bags down from £12, which is still too much in my opinion. I'd rather buy a cheap insulated bag and keep it in my bag or on my desk.

What do you think?
