I went to a big shopping centre where I can see there are four charging spots near the entrance.
However, two of them parked there were not charging at all. I guess it was just because it was close to the shops.
Personally, I don't drive an EV but raised my eyebrows seeing those dogs in the manger.
We live in a world wear ICE car drivers will park at charging bays, so ethics is different for everyone.
I would never think of using a charging bay as a car park.
I either am charging or I leave the spot.
