The queue was about 10 deep across and just a mass of people. We were in danger of missing our connection. It looked like they were training immigration officials and everything was taking 4 times as long. Once we were through I begged anyone with an electric buggy to give my wife a lift to the gate which was about 1km away as she was in considerable pain by then and they all refused saying they had to be pre-booked and instead offered me a wheelchair.
