Gross. That's why I carry a flashlight when walking dark sidewalks at night. Don't want to step in dog poo. Now imagine walking around avoiding stepping in people poo. Yikes! I've had to clean my toddler granddaughters shoes when she ignorantly walks over dog poo on grass. Can't imagine having to clean shoes on a daily basis in a shithole country. Or maybe they just don't bother.
They don't have to clean it off their shoes, they don't wear shoes.
