I remember reading that book when it clicked how frustrating the doors at my grad school uni could be: they had what is clearly a "pull" handle on both sides, but it only opened one way. They just added signs that said "Poussez" (push in French) on the push side because clearly no one thought about the design before installing it! It's unbelievable in the decades since that building my office was in was built, no one thought "hey let's put plates on this side so you CAN'T pull".

What’s also terrible is when someone adds “PULL” in standalone adhesive letters on one side of a glass door. There’s no backing on it and our brains can easily read the word “PULL” even when it’s backwards, so if I read it first I will pull from the push side.

I've heard it phrased like this: your door has an UX so bad that it needs an instruction manual (even if 1 word long).
