Visited on Sunday and charged with RFID, no issue.
At the time, the parking spaces were not painted and there was no lighting. The Aldi parking has a manual gate but it was left in open position.
Since then the parking spaces have been painted, as shown on the pictures they published to social media.
The location is also finally visible on their web map. Indicated 70ct/kWh credit card, which is what I saw on Sunday as well.
