I also remember a rental from Miami to Jacksonville, years ago, booked through a European intermediary. But the station in Jacksonville was very surprised when I showed up, the return took hours to process, and they charged a hefty drop fee (which the intermediary eventually refunded me). I was lucky that I had arrived super early at the airport, otherwise I would have missed my flight.
