I'm a business traveler for over 20 years, and my experience with the Charlotte, NC airport Hertz location would rate as the worst I've ever experienced. I'd confirmed various details of my agreement with Hertz's 800# but when I got to the counter (after waiting half an hour at the airport for a shuttle van that never came -- I eventually took the National shuttle and walked over to Hertz!!) the manager claimed they couldn't abide by what we'd been told and as a result our bill was almost triple the original reservation. Attempts to rectify with the manager on duty when returning the car were met with \"that's not our problem\" and \"well, you signed the agreement.\"  It's also worth adding that I've gotten nowhere with Hertz's corporate 800# (I was left on hold for THIRTY MINUTES) and their website (no response to email submission). I've never been treated so poorly. AVOID THIS PLACE!!!!
