Often times, when we go out for dinner or shopping and are driving separate vehicles, we will drop off the Volt at a charging station downtown so it can get some free juice & then drive the other car (Mazda) around town. Tonight, when we came back from dinner and the mall, we saw a Leaf parked in the spot next to us. It had left it's charging door open, assumingly so I could plug it in for them once we were finished. I plugged it in, and it quickly made a chirp and a blue dash light started blinking. I decided to leave a message for them on a napkin, which I tucked under the Leaf's windshield wiper. This was the first EV (other than our Volt) I had ever seen charging (or gesturing for a charge) at this charging station. Neat!
