Please Use Air Dryer - ok, how about NOT

Please Use Air Dryer - ok, how about NOT
Having worked with the best custodial staff I learned a lot about how clean or how unclean a floor can be.
I also know that when you develop the ROI and cost per square inch of toilet paper and paper towels you learn a lot about the cost of an employee using the restroom. I also know how you can add that cost into the overall compensation of the employee worth.
So why then do I dislike air dryers? I mean the dryers can save trees and landfill space. I was told that air dryers are cleaner.  That is when the flag goes up, why up...
I was sitting in the men's room pondering when another male enters, takes care of business, washing his hands and goes to the air dryer. Whilst sitting I feel all this breeze coming up under the stall and off the floor, blowing into my zone. There were bits of paper on the floor that ended up right in my face.
Alrighty, I do know from the conferences and seminars I had attended that when the toilet is flushed, fecal spray can travel a distance of 6 ft or more. This would mean that somewhere on the floor would be spray times the number of flushes. That residue then could be reintroduced to the art of flight. And into my face...

I find myself observing restrooms and hand dryers. And on occasion have dropped some, oh, let's say some crumbs and watch where these bits take flight.  That is an airfield trick to test for foreign object damage (fod).
So think about it. On this restroom floor is not only spray from toilet flushes, and have you have ever seen the floor around a urinal? Then you just came in from outside where birds and dogs might have left behind markings.
Ok, have someone on one side of a dung pile with one dead raccoon in the mix using a leaf blower and you on the opposite side. Yeah, that is what I am trying to explain.
Now try to leave the restroom after you realize the business only uses the leaf blower and you have to pull the door open by the handle. Do you know least than 40% of women will likely use the tornado creator if they even wash their hands?
