Makes my $24 over-charge seem trivial.
Although I have had larger car rental disputes. On National's Emerald Aisle at SAN last year, there was a minivan parked. I had my kids with me, so (just to be sure) I asked if I could have it for my Emerald Aisle rez. "No problem," the agent said, so I took it.
Sure enough, when I returned, I was charged several hundred extra dollars for the vehicle. I marched in to the office to complain, and the agent argued with me, refusing to believe I got the car from the Emerald Aisle! I stood my ground and the agent backed down, but it was a somewhat unsettling experience. I mean, how could I PROVE how I got the car?
At least with this dispute, I've got my email confirmation.
