My local co-op for about the last 10 years had a norman door, and multiple times a week I would pull rather than push or vice-versa. Then finally a couple of weeks ago they've sellotaped a handwritten push / pull on both sides.

So it mustn't have just been me getting it wrong every time!

Most doors in public places need to open to the outside for ease of evacuation in case of an emergency.

More doors should take a leaf out of USB-C's book...

Unfortunately either direction doors are harder to weather seal and energy efficiency matters a lot. Just give me a clear handle that indicates which push/pull and I'll do the right thing every time - this is cheaper as well (but it might not fit with your senses)
