I regularly run out of toiletpaper at home because my wife has a tendency to leave one and a half leaves of paper on the roll so she doesn't have to change it for a new roll. I usually end up walking to the closet with my pants down to get a new roll.
I have no problems with taking a crap in the woods and wipe my butt with whatever is available (leaves or a handfull of grass, bunnies absorb the best, but those are hard to catch when you're taking a crap).
If I'm without paper in lets say a public toilet in town then I either shout to the guy next to me to hand me some paper, and if no one is there I just tear off a halfmoon shaped piece of cardboard off the empty roll and use it as a sort of scraping scoop. If there even isn't an emty roll then I just pull up my pants and have a wash and some clean underwear when I get home.
I have no problems what so ever doing stuff like that. There's people dieing of hunger in this world, how could I consider having no toiletpaper at a specific moment as a real problem...
