SNAPPING: The Daily Yomiuri is reporting that “Bad manners are making people snap” more and more, noting that over the past few years there has been an increase in acts of violence committed by people who have lost their tempers in the face of people around them displaying bad manners.

Case in point: A 28-year-old high school teacher was arrested for allegedly striking a young woman on the head while riding a train. Before assaulting her, he reportedly told the woman, who was sitting with her legs crossed, that she had brushed his leg with her foot and her manners were poor.
