I received a call from the store while passing through customs. Since it took longer than expected to get through, the staff parked the car at the airport parking lot for me. While returning the car, I went to the store outside the airport, and the staff drove us to the airport for our flight home. Since I had bought QEEQ's Super Insurance, there was no need for any checks during pickup and drop-off as long as the tank was full. There are plenty of gas stations around the airport, so don't worry about not finding any.
