Visited yesterday without charging.
There are 2 parking spots painted green for the charger. The other spots next to the charger are reserved for Steiner-Beck customers. I guess the charger is available to the public as well?
Now that I review my pictures, I see there might be a Zaptec charger at the other end of the row of parking spaces, I didn't notice it while I was there. It's probably not public as I don't see any other networked charger here, but I'll need to check it out another time.
