Most of the cars I have rented in the last 6 months no longer give you a receipt when you check it back in ( some haven't even had anyone there ). For instance, yesterday at Hertz in Charlotte, there was someone in the return area and he simply said leave the keys in the car and you are good to go. I didn't have time to wait in line at the rental counter so I simply went to my flight. Yesterday afternoon I still had not received anything from Hertz stating that I had returned the car. So I called and after 20 minutes on hold an agent sent me a receipt.

If Hertz had claimed I hadn't returned the car, how am I suppose to prove it?
