Visited yesterday without charging.
I'm not sure what this location is exactly. It's advertised just like a freeway rest stop with a giant sign 600m before the turn (when coming from the south) and it even has the gas+EV pump sign, but it seems like all parking spots are exclusively for customers of the restaurant.
The 2 parking spots in front of the charger have an EV sign, but also the same sign that all other spots have with the "nur Besucher" text.
