The car rental company was quite friendly, but they said they would pick me up with a sign, yet no one showed up. I waited foolishly for half an hour. I asked other drivers who were picking up passengers, and they told me the rental company was inside the airport. But after leaving the airport, you can't go back in, so I had to walk 300 meters forward, enter the airport again from the departure level, pass security, find the rental counter, then they led me out of the airport again, walked another 300 meters, and back to the departure level, right across the road. I was sweating all over and wasted more than an hour!
