Lawyers have created this. I simply can't blame anyone for refusing to even push wheel chairs anymore. I heard of a pilot land in hot water because he was pushing a wheel chair and the person was wobbly and fell... somehow the pilot got blamed, and it was pointed out that pushing wheel chairs is not in the pilot's job description so you're assuming all responsibility for what happens.
There is a reason why some doctors are refusing to treat attorneys and their families. Can't say that I blame them. It's sad.
