I've used Hertz twice now in the past few months, both with my free Hertz #1 Club Gold membership from AMEX Platinum.

The first time everything was fine except Hertz took a month to bill my credit card and mail the receipt and I still haven't seen my Marriott Rewards Miles yet.

The second time, Thanksgiving in Chicago, they didn't enter the gas purchase option in the computer, and the promotion code I used for the reservation didn't take and I had to go inside and explain to the counter agent then manager that the code I used did not have a coupon associated with it, and after fifteen minutes they finally gave me the discount I was entitled to.
