hi, I need advice regarding parking tickets and if I'm required to pay them if they are given by private firms at a private parking lot. I was at a supermarket with its own parking lot. Before I entered the supermarket, I shopped across at another store before going in. When I came back, I saw a parking ticket given to me by a private firm for "unauthorized parking". If a private firm issued it, do I still need to pay it? I've heard that you don't have too.
