1. I had an appointment to pick up the car at 12:30, but since I arrived at the airport early, I got to the Dollar rental company around 11. They charged me for an extra day without any notice. When I discovered this, they claimed that picking up the car early means you get charged for an additional day. 2. Their promotional flyer mentioned an insurance option for 10 euros, which would cover glass and tires and reduce the deposit from 800 euros to 300 euros. However, they didn't mention that it's 10 euros per day. 3. The car did not have windshield washer fluid. 4. Traveling to Germany required a 50-euro fee, but they did not provide any sticker or receipt. 5. There was even a Hertz rental receipt left in the car drawer. 6. I returned the car with a full tank, had no traffic violations, and after thorough inspection and handover, 76 euros were charged two weeks later without any explanation.
