I can go you one better than that. 3-4 years ago, we were sitting on the beach in front of our regular rental house in Blue Mountain. It was about two o'clock in the afternoon. A girl came by walking her dog. All of a sudden, her dog took a big diarrhea dump in the water directly in front of our chairs. The chick never even batted an eye - just let her dog finish and was off down the beach.
I was so stunned I couldn't even say anything. My mouth was literally hanging open I was so shocked. In retrospect, I should have grabbed the dog's owner by the hair and forced her face into the doo-doo water that kept my wife and I from swimming the rest of the day.
