We may have a pier capable of handling 6 77Ws at a time, but we certainly don't have an immigration facility capable of processing a quarter of the passengers generated by those 77Ws. Thankfully I now have a chip passport but up until the end of last year there was a 3 or 4 month period when they couldn't be bothered to repair Iris and the queues just to get into the immigration hall could well be halfway down the new pier.
