The only real etiquette is to either stay with your car, or have an app that honks at you
when you are charged... and leaving a note in the window saying when you will likely be done !
How about the folks who are just using it as a parking space !
I love the all day Volt Parkers... WTF ? !
Oh man, I am so glad I seldom have to charge at public EVSE's. !
Even getting a couple of years free charging from Nissan has not made it worth the aggravation.
The worst one I have used is located in a shopping center with department stores.
The ladies will leave a car parked for hours, attached to a 30 minute quick charger !
I saw a couple fast charge, then sit in the spot eating sandwiches and talking on their cell phone long after they were done.
Meanwhile, I am trying to drag a cord 2 spots over from the EVSE to get going.
Only in an emergency will I go to this place.. because 3 times I have seen this crap..
and had to go elsewhere.
When the offender is a plug in hybrid.. I get more than frosted.
