we had this customer for 2yrs he always paid on time and was nice. He has a decent size fenced in yard and there is dog poop EVERWHERE. Last time I counted 36 piles and 10 of those where fresh. I have no choice but to run them over with the mower. Then the mower is full of poop and my boots are too. Trust me this guy isn't the type that would go out and pick it up. Should I charge him more? Or bite my tongue?
