In all seriousness, always sign up for the frequent rental car program so you can skip the counter. Almost everybody does it (National, Alamo, Budget, Avis, Hertz. Enterprise you still have to talk to the guy who takes you around the car, though you do get to skip the counter). You then don't have to show your credit card, just ID. It saves you a lot of hassle, from selling up and in your case to this credit card fiasco business.
(I think technically they may ask you to see the credit card but I've never had it happen).
With Hertz, how will I select a specific vehicle if I don't go to the counter and ask?
In my case, I needed the Toyota Sienna and not the Dodge Grand Caravan. (both are minivans)
Also had two additional drivers, so had to take them along so they could show their credit cards and driver's licenses, as well as sign the rental agreement.
