For me, it may be that the toilet paper roll needs to have the open end away from the wall. I don’t want to reach under the roll to take a piece! That’s ludicrous!

I sign papers with customers from all over the world, and if I get to sign first and need to add a date, I invariably go for YYYY-MM-DD from ISO-8601. If they go first it’s most often illegible to readers without any cultural context.
