When is a safe, not a safe?

When a bloke can carry it out of a bookstore by himself!

Many so-called safes sold at major department stores are nothing but fire-resistant strong boxes designed to protect documents from a fire but not cash or valuables from theft as they are easily removed or broken into using nothing but a decent screwdriver.

A proper safe of about the same size as a microwave should weigh 150kg to 180kg and be bolted to the floor, too heavy for some knucklehead to carry away.
