I can't for the life of me remember the name of this blog, but this guy related the absolute worst dump story....
He was on a private plane on a road show with clients as well as competitors. There was no real bathroom, only a pop up type thing under one of the seats in the back that had only a small curtain that only covered about halfway to the ceiling.
After sweating it out and trying to hold it in for 1/2 hour, he had to displace his female client from the seat and proceeded to pollute the entire plane with basically the **** that Fish described above. People tried to ignore him but that's pretty much an impossibility when you're in such tight quarters.
Reading that story made me cringe - really felt for the guy. Could have been any of us.
