There were many people in line, but the process was quick and well-organized.

Unreasonable charges. I booked through a rental car app, and the total cost including full insurance was supposed to be around 640 AUD, but they actually charged me over 2100 AUD. It felt like robbery. I drove over 200 kilometers to get the extra charges refunded, but the customer service from the rental company insisted there was no mistake. It's ridiculous. Even after I got my money back, the rental company still claimed there was no error. The difference was massive and they didn't investigate or protect customer rights. Who would trust this rental company?

Convenient

Very nice! My English isn't great, so I used a translation app on my phone to communicate with the staff at the store. They were very patient, speaking slowly into the phone one sentence at a time, making the whole process very smooth. Returning the car was even more impressive. I parked the car in the lot, went to the return desk inside the terminal, and they only asked if the car was parked before taking the keys and saying everything was okay. There was no inspection at all.

Very smooth and seamless. Kudos!
