I just left a call where there was a "strong odour"in his rental condo. I noticed a big area with black skack and crud on the carpet. The owner had given me keys and was going to show up when I finished. The stench from the area was revolting, but I dutifully worked on it and squirted a lot of deo around the entire suite. Turns out his tenant had died and was laying on that section of carpet for a week or so. I was rightly pissed off and told him why- his response was "couldn't you get the stains out?" I told him to contact his insurance agent and get it done properly. He was going to refuse to pay, until I threatened to call the city health department. And I will on Monday. What a disgusting friggin' trick.
