"Man asleep in A&E for hours"

I recently attended this dept. A young man was fast asleep on the chairs, with no one with him, he was there when I arrived. He was still there 3 hrs later, as I was leaving, sleeping off probably drink or drugs. He actually slid off the chairs, finished up on the floor, still asleep! He was obviously not getting treatment, or waiting for someone. There was security there, why was he not removed? He was never approached by anyone. It is not the place for a kip, it is a hospital, for sick & injured people.
