Smooth service process

Arrived early, but the shop was not open. Called to inquire, and they said someone would handle it when the scheduled pickup time arrived.

Even though only one person was in line ahead, it took a long time to get to me

The staff were extremely rude and ignored customer requests. They downgraded my reserved Mercedes E-Class to a small Toyota without permission. The staff also did not inform me that driving in central London requires a congestion fee.

The staff was alright; it was early in the morning so there weren't many people. I rented an Audi A4 wagon, but they gave me a Passat wagon, which runs on diesel. They claimed it came with a built-in navigation system, so no additional GPS was needed. I didn't bother to argue. Later, I realized diesel is more expensive than petrol in Europe...
