I refueled the car before returning it, but they didn't ask for the fuel receipt. However, when I returned the car, the fuel gauge wasn't full, which was frustrating. The staff asked for the receipt, and I didn't have it. But they said it was fine since the difference was small. Overall, it was a very smooth rental experience. I rented a Corolla but was given an MG, which was too large and affected my driving experience. No hidden charges.
