Last Thanksgiving we went on a wonderful holiday in the Florida Keys. We flew to Miami, picked up a rental car from Hertz, and drove away. There are a couple of toll roads along the way, but we had Hertz's PlatePass, which would work on those toll sensors. I've used similar things with other rental companies, where a few weeks later I receive a bill for the accumulated tolls.
Not with PlatePass, however. Not only did I get a bill for the tolls (about $11), but a $25 service charge on top of that! Turns out that Hertz charges $5 a day (up to $25), even on days when you don't run up any tolls! I'm stuck paying this, but you can be sure that I will avoid using and recommending Hertz in the future. Yeah, I found out that it's documented on the website, but it wasn't documented when I got in the car, nor was I given an option to disable it. So yeah, Hertz and/or PlatePass made an extra $25 off of me on that trip, but they will lose so much more than that in the future. This is what happens when businesses are short-sighted and go after the quick buck instead of developing long-term relationships with their customers.
