Cleaning the Subway

After having dinner with Marie and her other friends I entered the Subway at about 12 o’clock (or later). I was always wondering how they clean 24/7 stores, for example. Now I know how they clean the subway. They basically float it with a lot of water and soap. So it could happen to you that the stairs you want to go up look more like the Niagara Falls than anything else. Except for the soap bubbles.
