My work gets me into places otherwise I had not even imagined that existed. Today I went to a large, underground club with a big, gorilla like fellow, all dressed in black and with impressive 45 mm firearm at his side, guarding the entrance. It was early morning and few clients. The problem was a bad sewage odor, whose source they couldnt identify. The pic shows the pipe running under the ceiling - it had been painted over but the connecting isolation rubber rings were dry and ineffective. And being deep under the ground level, they had two wastewater pumping stations but not visible air vents. They have a maintenance plumber and he started to shout furiously at me contradicting my observations so I cut him short. I got the impression that the maintenance man purposefully had been maintaining the problem to keep milking the owner. Now I realize that I may have been endangering not only his income but his life too.
