According to the set plans, the front two pads are
perpendicular to the door just as Timo said. Furthermore, the following screencap from The Savage Curtain shows the hidden "console wall" (barely) and should put the debate to rest by proving that there is indeed another wall that is not seen in the Lincoln image. (The same one we see in the Bele image.)
It is still possible that the gooseneck wall was somewhere in the neighborhood of perpendicular to the door in this episode; but it is also obvious that sometimes the angle was acute and sometimes it was obtuse. The kiosk surely was repositioned as necessary or convenient.
