After going to the toilet half of people all over the world use hand bidet to wash themselves and the other half uses toilet paper.
It mainly depends on traditions of people and their nations.
A lot of places are called “international”. It means that they are visited by representatives of different nations. These are international airports, train stations, various tourist offices.
But usually these international places in Europe, USA and some other developed countries don’t have hand bidets in their toilets.
I think that every place like this in the world, which is called “International”, should have hand bidets in their toilets. So they can ensure the needs of people and justify the “International” title.
