Visited today without charging.
The charger was not reacting when I plugged the car in, so I couldn't see whether a credit card option would be offered on the screen.
The 2 green parking spots to the left of the charger are still there, but there's no longer any charger. I don't know whether that charger ever worked. There was an Alfen charger there the first time I visited but I never tried it and I never recorded it being networked. But I could have missed it, I'll dig back in my historic data at some point.
