They had QR codes in the airport and sent an email beforehand to have you pre-register with your name date of birth and drivers license number. I did this while I was waiting in line for almost 30 minutes at budget as there was no advantage of doing this before hand because you had to wait in the same line, however, it registered me for my Rental at the time that I put in this information which added an hour onto the rental, and they charged me for it. Then, when I returned the car, they did not go out and inspect, just asked me if I filled up the car. And then received a charge for fuel service, even though the receipt showed that I returned the car full. It felt like they were looking for every opportunity to add erroneous charges onto the price line price in hopes that people would not catch it.
