personally, I think GOq did nothing wrong, where I am- people are always yapping loudly to their companion on the way home from work, on the local bus. Sometimes, giving their day to the entire detail- and some people can get pretty graphic too, with strong language.
Sometimes, after a long day, no one wants to hear the other person’s day. And wants some quiet time before they arrive home and have to deal with whatever is waiting for them at home.
I think he did it to show how annoying she was the entire time. And GOQ – kol hakavod, I would have done the same thing.
