Nobody told them to shut up? Why?
The people should have at least bludgeoned them.
I guess you're not from a major city.
When I worked in manhattan, I took the train in every day. Most people take the train into manhattan, since there is no parking. Needless to say, when people are arguing like this on the subway or bus, you're best bet is to not say anything. If you say something, next thing you know you're involved in an all-out brawl with multiple people. I can't even begin to explain what Ive seen on the NYC subway--fist fights, someone get stabbed, a bum taking a dump on the floor, drunk/high people stripping, verbal arguments, physical assaults, etc. Just another day in NYC when you pack 5 boroughs with close to 9 million people.
