Although the CBP officer in HNL was surprised that British citizens were now included in GE (the memo had obviously not made it!) he asked a few questions on had I been refused entry, had I been in violation of customs, had I ever been arrested. Confirmed my details, showed me the video, it wall all very friendly (and air conditioned) He gave me some advice if the machine wasnt working and that was it. I got the confirmation email the same day
