Easy and great!

The charged too much money from my card. According to their statement, it should be only additional 20 AUD for fuel (although tank was almost full), but they charged 40 AUD.

Thrifty should hold the deposit amount on our credit card and not directly charging to it because when they return back the amount which is in foreign currency, I lose $30 for the exchange rate.

It was a terrible experience for our pick up at Perth. Despite that we provided our flight details and the fact that we would pick up the car past 1am, the Thrifty counter was closed and nobody was on duty in our terminal. We ended up spending over an hour trying to locate the last person on duty in a different terminal when a number of young kids in our group had to wait around in the cold. When we finally got the car, they were not able to provide the 3 car seats we requested, so we had to return to the pick up point the next morning to get the car seats
