As an exercise in clinical distance...

Holding it can also have not-so-fresh downsides.

In an emergency, in a public restroom... after the normal TP mechanics, you can follow that up with some TP that's been wetted in the sink. Then dry TP to dry.

Optionally, the tough and brave can add a tiny bit of whatever hand soap of unknown formulation is available. You'll need additional passes of wet TP to rinse.

Not-recommended: Some people carry those supposedly 'flushable' wet wipe products, but I think those are known to cause problems for plumbing and sewage systems.

(I'd better not get hit by a bus today, because I don't want this to be my final HN comment. :)
