That's why when I come out of stores I have the iPhone in my pocket and I don't take it out until i'm inside my car. That's one way they steal the phones when the person is on the phone and unaware of their surroundings.
Yeah, if the find my iPhone is enabled then they need to fix it to where it can't be disabled without a passcode or something. These low life scum sucking leeches have nothing better to do with their time.
