I have had a quick look on wiki. But was hoping for a but more personal insight.
I was talking to a mum who had a baby ill in scbu during a norovirus outbreak and she was chatting about how tough not being allowed visitors had been, especially as she had other children at home. Then she made a comment about how they had let her vicar in to see her and baby but he had turned up "in his dog-collar even though he doesn't normally."
So it got me wondering about how they are viewed nowadays
