A bidet does not substitute toilet paper...you use it after *facepalm*
Actually I find digusting that there's people not owning that(unless they take a shower everytime they use the restroom).
Idk man, a modernized bidet/toliet combo pretty much gets it done without any need for paper. When I was in Hokkaido at a ryokan, they had modernized bidets, and there was literally no TP in the bathroom. It would have bothered me, except for the fact, that when I wiped at the luxury hotel after bidet usage back in Tokyo, it turned out to be a waste of TP.
Iirc there also wasn't any TP in with the public bidets in the train station in Sapporo.
Also noise producing buttons to make people less likely to hear your poo noises.
