I volunteer in an elderly ward once a week. My duties involve making teas, handing out cutlery, handing out and helping people fill in their menus, tidying peoples tables, running errands for the nurses and just generally chatting to and keeping patients company. I phoned the voluntary services manager (whos number I found on the trust website) and came along for a meeting and there was a choice between elderly and outpatients. I can wear pretty much what I want and I have a lovelyyy green tabard!
