Visited today without charging.
At first I thought one of the charging spots was blocked by a truck, but it was actually an electric truck and was plugged in. Not ideal for public users of the charger if it's left plugged over the entire weekend though.
The contactless reader works. That's quite an investment to include a payment terminal at a garage, when so many "real" public locations don't have one 🤔
There are also 4 AC chargers with "Reserviert" parking spaces to the left of the entrance, not sure if those also belong to the garage or a different business.
