Around 1977, I was in a large cabaret on the west side of Yokohama station, the Hollywood, which subsequently morphed into a Yodobashi store.
It had a band and often featured previously well-known singers who were no longer a thing; 一節太郎, and the like. The Hollywood was sometimes used as the location of movie scenes. But I digress.
A young thug walked in, evidently heading to a table already occupied by others of his party. He made the serious mistake of passing by the table of someone he should’ve shown proper respect to, but ignored.
There was a kerfuffle that went on between two tables—I was one table away—and the ultimate resolution was that someone from the late-arriving thug’s table came to the offended thug’s table to make things right, doing something I had only ever seen in movies (仁義を切ったわけ), as the band played on.
If this had happened today, I imagine a bunch of jerks would take out their iPhones and take photos of it.
