Those public touch screens are grosser than public restrooms.

Exactly. And at least the restrooms are cleaned once or twice a day.

The touch screens appear to never be cleaned. Maybe because what will kill the nasty bugs such as bacteria and viruses, ie alcohol, etc. is caustic and can damage the touch screen.

Also, at some point they have to replace the screens because of wear and tear. They have probably included that in the costs.
