Call me conservative, call me what you want, BUT this is a whole new experience waiting to be tried in a court of law. Since nobody wants to take responsibility for their own stupidity anymore (coffee in lap at McDonalds, mouth burned by hot cheese Pizza Hut, woman hits shoulder on door frame while door is being held open by someone who thought he was helping her, in every case you know who got sued, and you know who won, go figure! Point is, someone will be looking for the monster at your store, gets hit by car, you end up getting sued or at very least getting a lawyer to help defend you in court. I might want to discuss this with my insurance agent first, better to be safe than sorry.
Just my humble opinion.
