The next time you’re out walking, pay attention to what you are walking on. You just might notice that the ground isn’t exactly clean, with the mud, grass, wet leaves, gum, glass, and general yuck.

Stuff sticks to the bottom of your shoes and you track it around with you all day long. Shoes are filthy, and no one really wants to sit in anything dirty. So be respectful. Please, keep your feet off the seats and off the walls. They should be firmly placed on the floor in front of you. And please don't take off your shoes and place your bare or stockinged feet on the seat or walls. Do this at home, not on public transportation. Thank you for your consideration.
