Bet they had to call roto rooter after each Berger visit. Of course Sandy will argue it is all OK since they did not post a sign in the men's rooom akin to the airplane signs advising just exactly what paper should and should not be put down the fixtures.
Off subject here, but in this Coachella Valley there's a large Mexican population; most public loos have signs in the stalls - en Espanol y Ingles - stating "Please put soiled paper in the toilet and flush".
Our plumber told us it's a "Mexican down home" thing that he'll find even in nice homes here - a box near the toilet where the used paper gets tossed....something to do with the 'pit sytems' they have in Mexico, so it's ingrained in them NOT to flush paper.
