A few weeks ago at my job, some lady pretended to fall down outside the store in about the most egregiously fake way possible. (she put her bags down and slowly got down on her hands and knees saying "OH MY GOD I'M TRIPPING" right in front of me) She made a big stink about suing the store and all this etc. etc., but it was then pointed out to her that she did it right in front of a security camera and she sort of pretended like she had been joking the whole time. It was entertaining.
God I wish I could. I would have enough material to dominate youtube. Alas, we have a very shitty and unfriendly camera system specifically designed so that only our main security office can get images or video off of it. That way, no employees can cover up their horrible crimes, because as I'm sure you know all theft in a retail store is because of the people who work there!
I don't think that was a scam - looked like she was backing up to pull into that free parking spot and didn't check her mirrors, decided to be a dick about it.
