I have a maintenance contract for a medical arts building. I  was called in one day because a dog had done its duty by the first floor elevator. Not only that but there was a trail of said duty from the second floor elevator to an office several hundred feet away. I entered the office and inquired as to why someone would bring their pet to the doctor with them and was told that the puppy was not yet fully trained and they didn't want to leave it home alone. You think!
