A couple of years ago at a very nice wine bar in Berlin I accidentally pulled a sliding door completely off its tracks due to it being impossible to work out how it was meant to open - it had a handle that I assumed you pulled on.
Luckily, I wasn't the first (or probably last) person to make that error.
Does that concept have a name now? That reminds me of this Japanese comedy sketch about doors: https://youtu.be/nq-2USGVoEE
The name of the concept is based on the name of the author of "The Design of Everyday Things", Don Norman. This kind of door is what spurred him to write the book, or so it's argued!
