"Curiously though, that right to make the rules on your property is arguably the right this nursing home is exercising, is it not?"
That is a good question. So here is my opinion....
People do not stay in these places for free. It costs a lot of money(I know you know this). I look at it as rent.( I know some land-lords prohibit smoking) When my grandfather went in with alzheimers( I stayed with them for as long as I could to help with him), they had to sell everything they owned. He did not get a "free" ride. So, at the cost some of these folks pay, they should have a little pleasure, if they so choose. It wouldn't be a big deal to have an area for them. They are in their last few years,months, or days, usually.
"that right to make the rules on your property is arguably the right this nursing home is exercising, is it not?"
But that is a valid point, I will admit. It is definetly a tough one to answer.
Gee, it's healthier than having AIDS
