Stopped by Dublin on my way back to SF from Yosemite, as we charged to 90% the night before at the Ahwanee (yes, I'm still calling it that) and we're able to skip the Groveland and Manteca superchargers.
The stalls were all taken, and two cars in front of me waiting to charge. The front car was a lady in her S but her supposed husband was parked next to her in a Cayenne turbo S, most likely waiting for her to plug in so they can drive off together. They must not have heard of the $0.40/min surcharge for parking at a stall after charging is done..
It took another 15 min for the next stall to open. When I finally plug in, there were 4 cars in line to charge. Now I know to avoid this place in the future!
