I think you are talking about bus Seiriken (整理券), which is quite complicated for me to understand. Therefore I always use IC card. I like Japanese IC cards for they are so beautiful and useful. I want to collect them as much as possible.
ヨーロッパの公共交通機関は悪夢です。On the buses and trains here in Denmark; there are too many noisy, inconsiderate bags on seats, food munching morons everywhere😆. 日本が恋しいです。 あけましておめでとうございます!
I think Japanese government taking outsiders so lightly these days, may be it is not good for Japanese culture.. You may allow outsiders but tell them to main decorum, atleast in your country as all we know Japan for good descipline, etiquates and honesty..
