Well just did EWR about an hour ago and it was a completely different process after answering "yes" to the food question.
They wanted me to fill out the card, which luckily I already had filled out as a back up. The guy asked me some questions and then I proceeded to walk out where the first CBP baggage agent said "They maid you fill out a card? Why, you don't need that

" I said I answered yes to food, and I went through the x-ray belt with a couple other pax and was still out in record time as I had only carry-on bags. The sticker did not get me or another GE guy to the front of the line at the baggage exit, but it was still fast.
At IAH last week, they guy just stamped my X receipt and I was off, and got front of the line everywhere.
I will note that my first Terminal B kiosk did not work, so I went to the next one, waited on my A/Cs pilot to finish and I was good to go.
I love the program, but I always get different info at IAH than EWR, re: adding a passport, types of food, and front of the line status.
Well, back to lounge drinks at EWR ^
Ciao,
