[Organizers] Problem with nondancing attender

Hi all, We are struggling with the best approach to deal with a community member who attends many of our dance events but does not dance (or pay). This person appears to have some mental illness challenges. He frequently has a small child with him. He has occasionally been disruptive in a minor way (or the child has been), and he has been escorted out a couple of times for that reason. He often simply hangs out in the building while the dance is going on, often in nondancing space. He is not easy to talk with. Reactions on how to deal with this person have varied across the different dance communities that use our space and different volunteers within those communities. We are trying to put together a common approach. Thoughts? David St. Paul, MN
