Funny, I just came back from the grocery store and there was an argument over by the bakery/liquor section. Only thing in my head was "Hopefully nobody pulls." Its actually been a thing I look at in crowded situations especially if there is a confrontation. It isn't rational at all, but I prep mentally for the moment I hear that pop. This is basically the world we live in.
as a new yorker, I rarely have to think that and people get into arguments often. most times you hope they don't throw something and miss.
