Over the years, at every level, I’ve seen rivalries and absolutely disgusting behavior by players off the field, getting overly serious over minor issues after a game, in the clubhouse, over a few beers, or even in a common lunchroom. Garbage people with garbage personalities who don’t know right from wrong. That said, only a very few individuals would ever act this way and very, very occasionally not shake hands but even they usually realize afterward that it was wrong.
Almost everyone knew enough to leave that nonsense off the cricket field and act like a gentleman once the match was over. Outside the ground, after the match, you can behave however you want, it’s still wrong, but at least play cricket the way it’s meant to be played.
