Paving Contractors

I had my car parked in Walmart parking lot Oct 14 3 am after getting off work at delongs. Forgot my wallet in my car thankfully cause when i went back out to get it walking towards my car I personally seen the employee wearing the leaf blower push a cart towards other ones but didn't watch to make sure it stopped. It didn't stop he kept walking off as the cart rolled towards the passenger side of my car I had to run to to cart and grab it just as it was inches from hitting my car. I yelled trying to get the workers attention he looked at me saw me trying to get him by waving at him and yelling but put his head back down and kept walking. I went back inside Walmart and explained to the only working what has happened she said she would let her manager know. When I left I tried again to get the guys attention with no luck nor could I get the wanna be NASCAR driver in the truck to stop so I could ask him to have the other please be a little more careful of others cars.
