Instead of "push" and "pull" the doors here say, well, some gibberish in Cyrillic, but it turns out that what it means is "to yourself" or "from yourself." Though innocuous, I think it is an important difference. These doors make no assumption about your intent; they do not demand action, only inform you of their function. "I open towards you, but, you know, only if you want me to." Nothing is required, you sign no metaphysical agreement, and there is no breach of contract when you look at the door, read the sign, and then choose not to go in. It's the difference between a popup ad and a hyperlink; there is no act of volition, no conflict of wills required to refuse it.
