Peter the painter

Peter the Painter is currently round my mothers house turning Fionas bedroom walls from Plum Purple to a lighter Amethyst. Should take 2 or three coats according to Peter Peter is extremley tidy goes home each night without a drop of paint on him, doesn't make a mess at all and even goes home for lunch. However, there is a problem he tends to use the main bathroom toilet for his Number 2'severy morning resulting in the armitage shanks looking like a Farmers done a 3 point turn in his field. How do you appraoch a man whose work is spotless but to be frank might aswell have a sprinkler attachment on his rear end when hes 'dropping the kids off at the pool' Perhaps spraying some Oust and gently opening the window may diffuse thesituation Im a bit more direct Id leave some Cillit Bang and a mop on the toilet seat.
