Wilcox et al were working in a hospital setting and just found that the air bacterial counts were higher around hand dryers than around paper towel dispensers, which doesn't establish whether the hand dryers are actually a source of bacteria. A more recent meta-analysis found mixed outcomes. So both the sign and the graffito need to revise and resubmit, ideally with a more comprehensive survey of the published literature.

I kinda got that sense from the moment that “AirBlade” sprayed all my germy hand water up into my face

Paper towels can be recycled

I can't fathom how those dyson piece of shit blade hand dryers were chosen at so many places instead of like a Columbia Vortex.

Those nasty ass dysons near guarantee you touch the inside of them, all while misting water back up towards your face.

All air dryers are trash, always have been.

tried using one of those hand dryers and it made my hands smell terrible

UV kills the germs. They should install lamps. Added bonus everybody gets tan hands.
