Is Netherlands being too lenient is becoming its curse

I’m an expat from Rotterdam. I was boarding metro in Schiedam centrum . There was this young guy looked like 18 who didn’t check in just passed the glass gate by barging into it. The gentleman before him asked him politely about it , which kind of offended the young guy and it lead to an aggressive behavior. He was so mad that he yelled so badly at him. I mean it’s Monday morning he doesn’t deserve it . Is he wrong for asking .? The aggressive behavior is uncalled for , why is this aggression for no reason .? Should netherlands government start being strict on its rules for it own good for the future generations.?
