Situation: I am looking for some printing papers on the shelf while there is another shelf on my right.
Alternative situations: I am looking for a book in the shelf on the right side of the cabinet. From the scanner I turn 90 degrees to my left and walk back to the opposite side of the room near the copier, then turn another 90 degrees left to fetch something from the shelf.
Question: Is the amount of rack on my left odd or even?
