Yep. And LP knows when it's likely an honest mistake. Just a couple weeks ago, I had one where I was running to the front of the store to go stop this guy exiting into the mall. I was going to just stop him and say "I know you didn't mean to, but you know the stuff you're taking into the mall is not paid for." I didn't end up having to do it; as I got to the door he turned around himself and made that "what am I doing" gesture and brought the stuff back in.
Intent or lack of intent is usually pretty obvious and easy to see.
