I want to chime in here. I rent a car weekly for business and until recently, I did it with budget. I travel frequently to Denver and Reno. When I go to Reno I always drive less than 75 miles and everytime I tell them I will bring it back full, yet everytime I get charged the 9.50 fuel fee. The last time I rented in Reno was a week and a half ago, the person helping me asked if I wanted to prepay or bring it back full, I told him I will bring it back full (it's my company's policy to fill up before I take a car back). When I brought it back I still got nailed with the fee.

I know my $5000 a year in car rentals isn't probably nearly as much as other people dish out, but I am sure other agency's will appreciate my business enough to not hassle me the way budget is. It's rediculous that each week, I have to wait in line and show them my receipts that I purchased gas so I can have that charge taken off.
