Data point: I had the same issue in two different hotels, a FS near the BUF airport and a SHS north of Philly. In both instances, when I checked into the hotel there was "solid matter" in the toilet. In both instances, this was shown to management. There was also a long hair on a towel at the SHS. My head is shaven bald and I had not yet used the bathroom. The FS gave me a free meal up to $40 while the SHS gave me 35k points.
