Come to Baltic states or Poland then. It does happen in either super old and not yet renovated downtown buildings or roadside establishments in the middle of nowhere. Old narrow pipes just can't take paper. Especially if someone loves to fold it few times...

I think I've seen that in the UK as well, but memory may be playing tricks on me.

I've been to Poland, didn't see it there either. But I suppose I wasn't on a tour of toilets!

I'm certain I haven't seen this anywhere in the UK (I live there).
