You don't see a problem with creating undisclosed fees? I've been renting cars for 13 years and I worked in car rental for 3 years, never in that time have I heard of cleaning fee nor have I ever charged one. The idea of telling a customer who came back with three cups in cupholders and a receipt and a straw wrapper in the center console that if they didn't clean it I'd charge them never would have occured to me and I worked for Enterprise, the most fee based company there is.
