Douchey or appropriate behavior in crowd control

Every day when I leave work, it's like a salmon fighting upstream. I work near a train station but the subway is towards where everyone is coming from. I'd say the ratio is about 100:1 in people going to the train to people going to the subway. It's a bit annoying needless to say.

As I'm leaving work today, I see a woman sitting at chairs near work and I hear her say to her friend "someone bumped into me yesterday and it is t happening today. She proceedes to take out an umbrella and use it as a lance against incoming traffic. If anyone got within 3 feet of her, she'd start aiming the umbrella towards their head and walked at a rapid pace. People did stay out of her way though. I thought it was incredibly douchey.
