Food poor

Arrival in USA is still a serious problem. Long queues for customs because not enough custom staff on duty. Process is duplicated while queuing. Diy system for self fingerprinting and retina pics and passport check. Then we still had to queue for official and repeat the process again. What a waste of time. A full hour before we could collect our cases after leaving aircraft.
