They changed their attitude immediately when I asked why the deposit in Germany was 300 euros while it was 900 euros in the Netherlands just because I didn't purchase Eurocar insurance. Their attitude was extremely bad, filled with contempt for Chinese people. When I couldn't hold back my anger, they became silent and awkward. I was very dissatisfied. The most outrageous part was when I asked about the late return calculation, they initially told me that if I exceeded the time, it would count as one full day. But when I asked again, they mentioned there is a half-hour grace period. Later, when I checked the contract, it stated that for the first 5 hours, it would be calculated at 20% per hour, indicating deliberate deception. I have rented cars in Europe and the U.S. many times, but this was the worst experience. However, the return process went smoothly, and the small Peugeot 208 I rented was in decent condition and was a new car.
