Why did authur Scott created paper towels?

Arthur Scott created the paper towel, because one day he received a train full of paper that he was going to use to make toilet paper with. But, the paper inside the train was to thick to make toilet paper. Recently Arthur had heard of a school teacher using pieces of paper for her children to blow their nose in, so as not to contaminate the bathroom toilet paper dispensers with germs. He decided to use his paper to do so also.
