It’s not as much a back room deal as it’s an understanding. If the parking attendant gets into an altercation with a member of the public, thay will need to call for the cops. It would be couter productive to book a cops car only to have to get that same cop to come and help later. Like clamping a fire truck only for your house to burn down.

The chef should be looking at getting rid of cops that can’t follow the basic licence place and parking laws.
