We arrive at George Bush Intercontinental airport on time, but as with my first holiday trip to the US almost 30 years earlier, the queues for immigration are long and slow. The automatic entry clears me but refers the Webmaster to the desk. It is a good excuse to moan. He'd forgotten to remove his glasses. Was that why it didn't recognise him as the same person in the passport photo? In the end it doesn't make any difference. There is apparently no fast track exit for those who get the all clear and everyone nearby in the queue has at least one member of their party referred to the desk.
