Is this even a legit company? Unmarked van. Did not offer business card. Asked a million questions about dirt being thrown down the drain after I clearly said that was not the case. Fixated on dirt being thrown down the sink. Wouldn't let it go. Pointed to dirt on the floor as evidence that dirt had to be thrown down the drain. Enough already! Never pulled outa camera or a snake. Just asked a million questions. Now I wonder if he was a fake?
