The service at the Frankfurt Airport branch in Germany was just average. When picking up the car, a hold was placed for a full tank of fuel. I booked a Benz C but received a Jaguar X20d diesel car instead. The car felt a bit small, especially the trunk, but the diesel engine did reduce travel costs. I was a bit late returning the car, having mistakenly entered the underground parking and returning it just over ten minutes late. I was charged an extra day because I picked up the car slightly early, despite confirming with the staff that I could wait until 9 AM to collect it. They agreed, but still charged according to the scheduled time. During the pickup, I noticed minor paint scratches and discussed them with the staff, so the actual pickup time was around 9:30 AM, but I didn't ask them to reprint the pickup contract. In the end, I had to negotiate with the manager at the branch, explaining the situation, and they ended up charging me a little under 15 Euros. Typical Germans, very rigid! While they weren't wrong and had a strong sense of contract, their service awareness was practically non-existent!
