If you steal a tester thing from a store?

Stealing is stealing, it's not yours to take. Unless you pay for it, it belongs to the store. Most business's call the police right away, and usually have the parents pick them up if the thief is a minor. I have seen it time and again where I work, usually teen boys, we catch most of them...business's keep a closer eye on teens, it's just the way it is.
