You have to admit, the toilet paper in a public restroom is pretty gross when you think about it. Since technology is taking off at a rapid pace in our homes and with many businesses, I think that in the next 2-5 years you will start to see an automated toilet paper dispenser in public restrooms.
The next questions is, how many squares will you get? 3, 4, 5? Who knows, but it should limit the amount of germs gathered from using a public restroom.
