Diarrhea at work:

If you have the misfortune of hearing someone having a mean case of explosive diarrhea, be sure to give them a wide berth. The every-other-stall-spacing rule may need to be expanded at that point. 

In fact, it may be best to take your own pooping to another floor or another restroom in the building. 

Also, never make eye contact with that poor pooper. He is in enough pain already. 

If you are the unfortunate one having diarrhea, always take the farthest-away stall. And learn the Courtesy Flush (see other post).
