Hi firstly welcome,
Just a thought I wonder if your porter will be wanting to be reminded of work after he retires, I certainly would not. Has he a hobby. I could not wait to get away from violent kids, they offered me the playground school bell which I used, (read into that animals trying to kill each other) suggested to the the head where he could deposit it.
As roy says where are you from, how big is the hospital, have they no technicians dept who could do this.
regards
Bob
