If it smelled like weed, he should have noted it in the pre-inspection. I take my iPhone and video the inside/outside of the car. Takes all of two minutes. Rented a car on the east coast and the driver wiper was trashed, bought a replacement at an auto store, kept the receipt & bad wiper. My wife was like, what are you going to do if the don’t reimburse you & I said I’ll take the good one off and they could have their old crappy one. They gave me $25 credit so I was ok with it.
He did, they wouldn’t give him another car. Hertz is the worst.
