Visited on August 10 and charged with Google Pay without issue.
The charger is the very last parking space at the exit of the gas station. It's a one way, you are supposed to enter and drive all the way around, but you could also quickly cut through the "no entry" sign.
If you had to charge a large vehicle, you could park on the public parking side on the "no parking" cross and pull the cable there.
It looks they already installed the foundations for 2 additional chargers in that row of parking spaces, for a total of 6 charging spots.
Contactless is 65ct/kWh, 50CHF reservation.
The SOCAR CHARGE flags are nice, but they might be in the way if you park a tall vehicle in the parking spot to the right.
