Great list, but I have one addition

CHATTY NEIGHBOR

You are doing your best to take care of business quickly and efficiently. After carefully choosing the most appropriate stall (based on cleanliness, sufficient bath tissue, and a minimum one stall separation from a fellow patron), your privacy is invaded by a newcomer who wishes to engage in conversation. Only under an emergency situation should any verbal exchange take place at any time with an occupant of a closed door stall.
