I flew to Washington from Cape Town and had booked a car through Rentalcars.com. After 24 hrs of flying I reached the rental outlet only to be told that the would not accept my international drivers licence and I did not have my national licence on me. I was stranded and now had to check into a hotel and book a train ticket and two taxi rides to get to my destination costing 300$ and Rentalcars.com refused to refund me anything. No car, no apologies.
