I noticed that the clock for AdBlue on my tank in Germany has not started for a long time with the amount 0 Euro, but 0.30 Euro and approx. 0.3 Liter. Even if you don’t want to fill in at all, but only want to display the price at the column, this amount of the credit card will be charged. Without this ad you will not find the price (no price address at the tank). The customer will not be informed about this before. Although there are only 30 cents each time. Nevertheless the question: Is that allowed?
