Eastern Europe (and elsewhere in Europe?) they still use tree bark and other coarser wood materials for TP. Best to bring your own favorite.
I was deployed to Uzbekistan in 2004. If the portajohns ran out of good ol’ U.S. style TP, they substituted good ol’ former Soviet Union style TP. I have a souvenir roll of that Russian stuff. Not like sandpaper, but close.
And in a restaurant in Samarkand the WC was an elevated hole in the floor. I only needed to take a whiz but noticed that used TP went into a wastebasket next to the hole. Ewww!
My deployment to an independent republic of the defunct USSR taught me one thing: nothing, I repeat, nothing bad I ever heard about life under communism was ever proven to be wrong. The socialist quality of life sucked beyond all imagining; the middle aged Uzbeks told me so, and I swear their younger generation was nostalgic for Josef Stalin & they told me so too!
Humble toilet paper a measure of the general societal quality of life? You bet your bippy!
