many years ago my sister, who lives on the 'main' road was daily finding a fresh hoo normous dog turd deposited by their front gate in the morning as she set off for work, so one day my brother in law (who drove the bin lorries at the time) took a late start but still got up early and sat in the bedroom window on turdwatch. He found the culprit (we had guessed who it was -he was notorious and actually proud of refusing to clean up after his dog.) who only lived a few doors up, so Mike quickly went downstairs picked up the still steaming growler (he was wearing his full council PPE including gloves) and followed him home, knocked on the door and just handed the turd back.
It never happened after that.
