Who here has worked as a Porta Potty sucker ?

Growing up we had a septic tank. City put sewer lines in, mandated everyone tie into them. Had to have the septic tank pumped/filled or removed. The poop pumper guy was kneeling down by the open tank. Mackey, our Collie we had, jumped on folks when they were kneeling down. She jumped on him from behind...needless to say what happened.....
