California Taqueria On Court Street Obviously Angered Its Landlord

Oh, boy!  A reader sent me the photo above, which was taken on Monday afternoon.
It would appear that California Taqueria at 187 Court Street at Bergen Street, has angered its landlord, who has gone to great lengths to shame the Mexican eatery for non-payment of rent.
A car, presumably owned by the landlord, was parked right across from the restaurant.  It sported a huge sign on its roof, announcing that California Taqueria owes $312,000 in back rent, refuses to pay up and "continues to abuse the landlord, a WWII Vet."
Think this will help or will it drive away customers, making it even harder for the restaurant to pay the rent?
