Only one star as I can t give none. When flying in recently with a visually handicapped person the passport control was absolutely atrocious. Only one of six desks open, everyone else trying to use the automatic gates. A stroppy official made us leave the desk queue even though we explained one of us could not see. He then pushed my companion into the automated gate, scanned her passport and shouted unhelpful instructions at her, completely ignoring her disability. No one to complain to. Dreadful.
