When my wife and I were in a church choir, we were considered "volunteers" by the church, and the church's denomination headquarters determined that all church volunteers had to go through that denomination's workshop on avoiding impropriety or the appearance of impropriety. At that time, we had adolescents in the adult choir, and it took a week for a friend of mine who was a choir member to ask one of the adolescents whether it was okay if he still gave her a hug. She said "Yes, of course!".
