I'm going to say there could be more to the story. The unplug guy is pretty polite. I don't see 'all the chargers' from the footage.
You must live really far way from that charger with a 100D to need to plug in overnight or longer to an L2 charge. The video as at 3:36am when City Hall is not open.
There used to be 2 L2 stations, but now only one. Drivers report there is only 1 connection working. If the 100D is parked there constantly to save a couple of dollars, that is the world's cheapest and most self-centered bastages in the area, especially if he doesn't use the building every time he charges. Not to say that's the case. But who plugs a long range EV into a low-speed city hall charger at 3:30 am if they live in the area?
