Agreed it was not the most elegant way to stop them, but she gets points for trying.
Woder if Wal-Mart is even thinking of paying for her medical care. I have my doubts. The only thing I am certain of is that Wal-Mart seems to think it is less expensive to let products go out the door than to actually do anything to try to stop it from happening. Then they can raise the price $200 and put a sign up saying the price is now cut by $0.75 and make customers think they are saving money.
stay safe.
