As a UK resident, I feel a pang of embarrassment and sadness and anger as I see how non-residents are treated when going through immigration control. Heathrow immigration is the worst. It's depressing, oppressive, cold and ugly. These are probably deliberate choices. On several occasions, I've seen customs and immigration officials behave aggressively, usually fidgeting with night-sticks (truncheons) in a way that suggests that they are itching to beat someone.
