I work onsite for my client, and they are located inside a large complex with numerous other organizations. The parking deck to which I am assigned lies beneath the building. About 2 years ago, I started taking the stairs instead of waiting on the elevators. I had two main reasons for doing this:
- The elevators are unbelievably slow and prone to breaking down
- This would provide a meager amount of exercise on the way to sitting in a cubicle
One major drawback of taking the stairs has been this highly unpleasant smell at the bottom of the stairwell. It distinctly smells like some sort of sewage leak in the building’s infrastructure. For the longest time I was sure it would go away whenever they got around to repairing it. Instead, they would douse the entire stairwell with this industrial-grade odor killer, which would bring me closer to vomiting than the initial odor. An additional curiosity to this mystery was that I would sometimes smell cigarette smoke near the source of the sewage-based odor. Smoking in the stairwell is forbidden, but even more freakish to me was that someone would decide to smoke in a confined area with that sewage smell swirling around with their Marlboro reds.
The mystery has been solved.

Apparently someone likes to sneak into the stairwell of this secured-access building and have a smoke and a pee. The white foam near the door is caused by a heavy dousing with bleach from the building custodial staff, who apparently also crafted the confrontational sign. I can only speculate on how the offender might retaliate to this escalation of the conflict, but I certainly hope solid human waste doesn’t enter the picture.
