Thank you, Zahavasdad for answering the first two questions posed by elik.
elik,
3) why are the signs unclear not stating who can park there??
The sign is actually irrelevant; it’s the law that counts. This is the same problem as in my driveway thread, namely that people take liberties with the property of others. The driveway belongs to the property owners. You need their permission to use it.
Under the law (as well as halacha) you have permission if you are a customer. You have no permission if you are not a customer. It’s really quite simple.
I am not the only person in Brooklyn who wishes he could afford such a “staff” at my private driveway.
Please reconsider your views.
