Back in 2018, the Japanese team cleaned up their entire dressing room after loosing in the world cup. Their fans also cleaned up their side of the stadium.
This year again the fans have minor news stories for staying behind after games their team has not even played in and cleaned up all the rubbish.
AIBU in thinking that there is not enough coverage of these positive behaviours, instead all we see is UK news bitching about lack of drinking alcohol ect. May be we should just take a bit more notice of how other countries are conducting their selfs.
