How did I miss the point? I said exactly that. The fact that there are not enough resources is meaningless and unrelated to my post, they will just join the manual queues which would be longer and take even longer with the current number of immigration staff. No different to when I travel to EU on UK passport at times and had to queue for 1hour plus on a few occasions because they had 2 people and 2 desks open out of, say, 12 manual desks that were closed/unmaned. How is this different?

This is about fairness, nothing else. if people have to queue for 4 hours that is irrelevant. Perhaps someone would then do something about it. Why Americans or Canadians , Aussies can use automated gates in EU terminals, but not Brits? Makes no sense! They are not in EU either but can use automated gates.
