NBC Chicago reports a woman finally had enough after she stepped in her neighbor’s dog’s poop. Again.

Susan Miller first took the offending poop off her shoe, and wiped it on her neighbor’s porch.

Police report that Miller next "threw dog feces at the [dog owner’s] sliding patio screen."

On the grounds was a sign informing dog walkers to pick up after their pets.

Miller reportedly "uprooted it and placed it on the dog owner’s patio."

As if that weren’t enough, the angry woman topped it all off by allegedly placing several small, green plastic bags of dog poo "on various places on the patio," reports the Naperville Sun.
