Shit I Hate: People Who Sit in the Buffer Stall

This is not 'Nam. There are rules. For example, when there is one person in the far left of three stalls, but no one in the far right stall, under no circumstances should you enter the second stall, unless it's to pull a hilarious Karate Kid style prank on the guy in the left stall. In every other circumstance, you should enter the far right stall. And frankly, if there is someone in both the far right and left stalls, then you should choose a different bathroom or hold it until the situation resolves itself. That's what I do. Hell, I did it today. Walked in and walked right back out, because I sure as shit (pun intended) don't want to sit in the buffer stall and then have the guys in the other two stalls finish their business, leaving me as the asshole (pun intended) sitting in the second stall making life uncomfortable for anyone else that might walk in.
