Situation: There is a paper stuck inside the printer in front of me. I just managed to get it out and about to dispose of it using the shredder on my right.
Alternative situations: I am waiting for the printers on the left side of the scanner to finish printing some advertisement materials. From the shelf I grab some ink, then turn 90 degrees to my left, walk to the printer, and turn 90 degrees to my left again to face the printer and install the ink.
Question: Which direction should I go if I want to scan something?
