Visited this location back on Sunday February 16, 2020.
The charger was under a short roof in front of the garage. Only one of the spots was painted green, the other spots were customer spots.
There was a car plugged in but I didn't see the owner, so I didn't know if it was left there by the garage over the weekend or if it was a regular user. My closeup pictures show the car had been charging for 22 minutes so it must have been a "real" user.
There was a contactless reader but I don't remember testing whether it worked.
On the charger there was a sign saying you could get a coffee for 2 CHF during opening hours.
