After the treatment from this station, I'm swearing off Hertz for good.
Hertz now does a credit bureau check before they will rent you a car, and the rental agent looks it over and decides if he is going to rent you the car. I know that every inquiry is recorded and lowers the credit score, so I did not give permission to view my credit report. The agent was pissed off at me for not wanting him to look at my credit report. When he raised his voice at me, I called Hertz's customer service to complain and get it resolved. It seems that the policy is now company-wide, according to the customer service agent (both the policy of having station agents look over customers' credit reports AND the policy of treating customers like gutter trash -- the person on the phone was just as bad as the person at the LAS station).
(I'm not mistaking the credit check with a credit card authorization. Their new policy is to get the credit bureau report on all rentals, according to the station agent at LAS and the customer service agent at Hertz.)
