You have done shows on sewer workers, but what about the people that clean up what doesn't make it to the sewer? I have cleaned bathrooms in a retail store and it can be very nasty. Men miss the toilets or urinals and it becomes a stinky, sticky mess. Women that do not dispose of feminine napkins properly. Not to mention what you have to do when the toilet clogs. Men husband currently cleans a Nordstrom store at night and you would not belive the stories I here.
