A: You are a special investigating officer. You see a person with a big dog that is pooping on the sidewalk. You know that dog owners have to clean up after their dogs. You can fine them for 80 pounds if they don't have 2 poop bags with them. You go over to talk.
B. You are the dog owner. You forgot the poop bags at home, but you live very near. You can quickly go home to fetch them.
