Agreed they should’ve made arrangements with the owner. At the same time there is plenty of public parking between Malibu and Zuma. $8 on the week day, $20 on the weekend. These two can afford to buy a couple of spots each (to ensure they don’t get the doors dinged).
They’re in a parking lot for shops. I don’t see a problem. The worst problem there is the giant storks in the palm trees above, who make the biggest bird plops in the world. I’ve seen them aim and hit butter leather convertible seats.
