I guess it goes back to my roots in the church. Not to go religious on you, but Jesus in John 13:14 states "If I then, your Lord and Master, have washed your feet; ye also ought to wash one another's feet." The story goes that Peter did not want Jesus, who he considered his Lord to do something so menial as washing his (Peter's) feet. We refer to many of our church leaders as the "minister" which in effect means servant. Food for thought.
