According to a recent Stanford University study your smartphone touchscreen -- that's yours; not mine -- may have 18 times more germs than a public toilet flush handle. I wonder how this pay phone would fare in comparison to your personal mobile device? With so many personal mobile phones it may just be cleaner. If I were forced to use this phone I would sanitize the receiver and use a tissue to press the buttons. Back to your smartphone. If you avoided public touchpoints your phone could be just as clean as mine.
