Two-Day Trip in Heidelberg, Not Used to the Small and Frequent Intersections in Germany! There Are M

The car was pretty good. However, because one gas station near the airport was under renovation and another one couldn't take credit cards for some unknown reason, I had to return the car without a full tank. For 440 km, the average fuel consumption of the Toyota was 6L, and they charged me €70.62. They showed me the receipt on an iPad and said they would email the bill to me later. In the end, I didn't receive anything in my email, but my credit card showed a charge of over €83, which was extremely frustrating!
