Firstly, the rental car counter at Paris airport is unbelievably slow; we waited a full hour and a half before it was our turn. Secondly, the counter staff didn't care about the car you reserved; they just kept pushing you to rent more expensive cars. We ended up with a car costing 1300 RMB per day. Finally, when we returned home, we were greeted with traffic fines totaling 3000 RMB, very frustrating!
