Truthfully it’s a design issue. If people keep coming up to a door and pulling on it, it’s because the design of the door is instructing them to do so. Design imparts information. A door in a home can have simple knobs - anyone living there can just learn which doors to push/pull. A door in a public space instead needs to be designed to tell people how to operate it, even without any labeling.

A door is a simple device. It shouldn’t require reading labels or a manual. It’s operation should be abundantly obvious. After all, even those who don’t speak the language or are illiterate need to be able to operate doors. A door that needs instructions is one that is poorly designed.
