I normally find it enjoyable to see owners walking their dogs indoors there, but I was never privy to one excreting on the walls.
About a half hour after that occurrence, I was sitting at a table enjoying a coffee when I heard the yipping of a small dog. Guess who? That's right: the same dog. An owner that allows their dog to behave in this fashion is not only providing a disservice to the public, but very importantly is not being a leader to her pet, who desperately needs leadership (and good manners). That poor little dog's owner deserves a spanking.
