That's the thing that is driving me insane! If it was legitimately someone witnessing a child being hurt than you would think they would leave their name and number so that I can contact them and find out a description of my "staff member" and the fact that they would have had to follow me to my street to get my info from my sign. otherwise they don't know me from Adam. This is why I'm thinking it is someone trying to stir up trouble. I think from now on I will only frequent my backyard playground. I don't need the drama from potentially other jealous or malicious providers.
