Bad Door Handles

These doors (which I found at Southdale Mall in Edina, MN) do open when pulled...from one direction. From the other direction, you have to push the doors to open them.
So, regardless of whether they afford to be pushed or pulled, the doors will inevitably be unusably. Their use in an inherent contradiction. The same exact design means PUSH from one direction, but PULL from another. My brain just can't handle that unintuitive of a conceptual model.
The really annoying thing is that there is another set of doors just beyond these. And those doors are well designed--when they're to be pulled, they have a handle, and when they are to be pushed, they have a horizontal bar that one couldn't pull if they tried.
