Wanna know something? In the men's washroom/restroom/bathroom at work, when someone flushes the toilet, you can hear a gurgling from inside the drain pipe (in the floor). Wouldn't you hope that the wastewater pipe from the toilet goes completely isolated out to wherever it goes (and I'm sure it's here in stinky Milpitas)? It's not comforting to hear that open-air gurgling after a flush. This is how diseases spread. Gross.
