I had that happen to me, too! Only it was just the opposite. My dog, Bruno, weighed about 19 pounds (dachshund/cocker spaniel mix) and this guy yelled at me for not cleaning this pile of poo that looked like it came from an african elephant. His wife didn't laugh at him, but, I sure did. I didn't say much except for that the size of the poo was almost my dog's weight. People are so self righteous sometimes. But, I just laugh, and, thank my lucky stars I'm a compassionate person with a sense of humor.
