I still don’t get this sign… hope it makes more sense in Korean and Chinese than in English. Do they mean, wait to flush the toilet until you’re finished with using the toilet paper?
Overall I always find it fun to find weird English phrases in Japan. No wonder the word “Engrish” was invented. Since I’ve really seen some signs that doesn’t make sense at all. Other times I get the meaning, they just make it sound more complicated than it needs to be. Like this bag from a accessory shop in Fukuyama.
