I've been to the Topanga store multiple times, there are two other J 1772 chargers for electric cars in the same alcove of the parking structure. You can see a model S plugged-in in the photo. Though charge rate much slower than Tesla high powered wall charger. I agree it's disappointing not to be able to put my Tesla next to others and enjoy an upfront parking spot. However charger abuse is not isolated to this location, at the Hawthorne Supercharger people were leaving their cars for extended periods of time occupying spaces beyond the time needed to complete a charge. As a result of trying to avoid that location.
LAST YEAR I MADE THESE RECOMMENDATIONS TO TESLA HQ:
1. MODIFICATION TO THE TESLA APP TO ALLOW USERS TO COMMUNICATE WITH ONE ANOTHER WHEN CHARGING, LOCATION SPECIFIC. For example at a Tesla plug-in location an owner could post when they're planning to return. In the case of roped off parking spots to prevent ICE abusers (such as in Century City), owner could text store and receive unlock code for the gate or combo-lock on charger. Plus owner could be text messaged through the app reminding them their car has charged, that somebody is waiting for the slot, that the store needs the spot to charge a demo car.
2 App to indicate WHEN THE CAR IS APPROACHING FULLY CHARGED SO THE OWNER COULD RETURN TO FREE UP THE SPOT.
3. App can allow Tesla to monitor abusers or allow others to report charger abuse.
I understand how frustrating it is to drive up, find all slots occupied but three cars out of six no longer charging. Often it's not a big deal, 90% of the time I've got more than enough mileage in the car however driving a Tesla with half of range of my former car and considering life's unpredictability (Like when my son fell in OC at a concert, broke his arm, and I drove an unanticipated 120+ miles), it's always nice to stay near full. This formerly rare event will continue to become commonplace as we add 30,000 model S/year.
Conclusion: It's time to update the app to further support and augment the ownership experience.
