That's exactly the experience I had at Terminal C at EWR on 1/17. Mid-afternoon arrival from BOG, immigration was very quiet, no ticket printed by GE machine but I did notice an agent with a tablet as I exited. But nobody stopped me as we left customs. In 40+ years of international travel, that was a first. I even had the receipt for my new leather jacket handy to prove it was under $800 (bargains abound in Colombia) but nobody asked me. I almost felt like I was getting away with something.
