I'm with Patrick D. in that I'm a Gold Plus member and I've haven't dealt much with many of the staff. I have never had an issue with my reservation and have always been in and out of this place pretty quickly. No issues so far.
Of course, if I was renting for personal reasons, I would choose another rental car agency because Hertz is generally the more expensive option. They usually have better car options, though. So if you care what kind of car you're driving and don't mind paying extra, Hertz would be the way to go.
