Situation: I am grabbing paper towel from the paper towel dispenser after emptying the trash can to my immediate right.
Alternative situations: Throwing a paper towel I got from the dispenser in front of me in the trash can to my right after I just washed my hands in one of the two sinks behind me. I am facing the paper towel dispenser to get paper towel to dry my hands with, trash can to my right.
Question: Is the number of sinks behind me odd or even?
