Here you will not find a good and kind attitude. Believe me, it’s not worth it for such people to take part in the upbringing of your children.
I live next door. The school grounds are open, free for passage. I passed by this place on a day off with a small dog (a friendly corgi, on a leash and in a muzzle, I always carry bags with me and clean up). A man came up to me and said that the owner did not like that someone could walk here, and that I should get lost.
The private area must be fenced at least. Apparently, the owner of the establishment is used to solving issues with rudeness, rather than observing basic safety rules and mutual respect.
Think about it and choose a better place for the child.
