I beat you to it, stopped by about 850pm this evening.
My own thoughts are they located the chargers down a little too far away from the main entrance, making them more difficult to find. Right near that unfortunate ramp behind a cafe where the workers smoked cigarettes out back. Surprisingly lots of non ev cars zipping through this narrow lot. Also encountered a roaming homeless person wandering around the parking lot eyeing the fancy cars, so we choose not to leave the vehicle unoccupied. He wandered past our car at last three separate times.
My advice is only use this location as need be, and preferably during daylight hours. The locals nearby after dark make one feel less confident about leaving a very expensive vehicle charging unattended. Even in Los Gatos. Would like to see stationed security or police on a regular basis to help curb the perceived riffraf.
