Manipulation von Wasserflaschen an japanischen Schulen löst Alarm aus; Schlafmittel, Desinfektionsmittel gemeldet

Is it becoming common for students to bring their own water bottles to school? It used to be students just drank from the water fountain. To think about it, it seems I’m the only one drinking from water fountains at parks and in buildings. To come to think about it, water fountains at stores seems to be disappearing.
