I was thinking the same. I've heard that people who urinate or deficating in public and/or strange places are very likely to have a mental problem. Either that or the guy was so angry and disgruntled and he just really wanted to tick people off.
No matter what the reason, I wouldn't recommend anyone putting him in any possition of authority.
I used to work in several different "group homes"
Many of our patients with more severe disorders did not have "good toiletting habits".
We ar coming up close to lunch, so I will not elaborate.
However, I view this fellow's behavior in the eleavator as a sign of a possible aberation....
And of course, we all know that "I've heard that..." is a perfectly sound argument to make during any reasonable debate.
