I was harrassd

I was harrassd by the parking attendants knocking at my window telling me to exit my car as I am not allowed to sit in my own car. I asked where is the written rule for this. It doesn't exist. They merely have to go on peoples cat to tell them this. This is beyond insane. No freedom with ur won car when u have legally paid for parking, spent money inside shops while taking a breather to go back to the casino to continue with your business
