Thank you for the dignified responses. I had nothing to jot down a note with, but I have since printed cards to leave for anyone EV parked and not plugged.

What are the possible choices an EV car can have in an EV charging spot?
-Plugged in and charging
-Plugged in and done charging (service is off, plug still plugged in)
-Not plugged in at all.
The first two are very mild "infractions" of etiquette, but the third is inexcusable.
In the second case above, -plugged in and done charging, I have no problem unplugging to use the charger for myself, and if it were my car and I was plugged and done (well, first of all, I'd know, and I'd go move the car) I would be glad to be unplugged so someone else can use the plug.
Parking in the EV charging spot and not being plugged in at all is the equivalent of ICE'ing over the EV spot.
Thank you.
