So non-citizens should avoid visiting US. Got it
My fondest border experience was many years ago when entering France; this was before the UK had joined the EU. (Our later exit was dumb, IMO.)
Anyhow, a youngish officer - probably mid-20s or so - examined my passport while asking questions, in perfect English. His voice was even and his demeanour calm and professional. Then he took a step back, closed my passport and put it in his pocket. A few seconds later, he started laughing and said: "The look on your face. Priceless. Welcome to Paris."
He really had me and I saluted him for that.
