Situation: Changing the trash bag by the door. The trash can is full of wasted paper from the copier on my left.
Alternative situations: I am placing my gum inside the trash can in front of me, that is below the manual pull station to the left side of the door. I threw my trash away into the trash can and then headed out of the door to my right.
Question: What is the color of the trash can that I am emptying?
