Small-scale money savings option
Use the bathroom when you're away from home, especially if you're in an area where you have to pay for water, and usually a parallel (or included) sewage charge along with it ...
... in addition to having to buy toilet paper.
Here on the farm, we use water from a well ... and a weeping tile bed for sewage disposal, so the only immediate cost is for electricity to run the pump.
The owner should, of course, set a little aside, from time to time, to pay for cleaning the well, replacing the pump, pumping out the septic tank and (horror of horrors) ... replacing the weeping bed following saturation.
"Saturation" - that's a good term to describe the frequency of political ads, prior to an election, no?
