Round trips from Munich to outlet village, Neuschwanstein Castle, Zugspitze, King's Lake to Salzburg

Picked up a new car with only 1000 km, noticed the driver's seat armrest was dirty. Staff said they only record the issue but don't clean it, advised to go to the exchange location if not satisfied. Budget's approach is understandable. After a day's drive, the tire pressure warning came up. Checked at a gas station: standard pressure 2.3, but the tires were at 2.1, 2.0, 1.9, and 2.2. For a new car, how was it driven by the previous user? The staff confirmed it was full of fuel with no scratches. After three days, they still deducted 11 euros from the deposit, claiming it wasn't full. 7 euros for fuel plus 4 euros for tax. If it was confirmed full, how can they later say it wasn't? With 7 euros of fuel, this hybrid should at least run 100 km. In the end, Budget is understandable, but it's much worse compared to Budget in the USA. Everything never happened in the USA but all happened in Europe.
