Dealing with nutcases on the bus?
I ride one of the long haul interstate buses into the city for work. Had a lovely incident this morning where a lady flipped out on me hard after the bus discharged at Port Authority. Earlier, when she got on, she decided to sit right next to me in the back even though the bus was empty, and promptly began having a loud conversation on her phone. I got up with an exasperated sigh and sat somewhere else because I could hear her over my headphones. When we all got off, I noticed her walking right next to me, loudly telling me that I didn't own the bus, and she was following me for several minutes through Port Authority while yelling at the back of my head. People were staring, but at her, not at me. I was not reacting to her at all.
What do you even do in a situation like this? I don't have viable transit alternatives so it's not like I can just take a different route. She looked so generic that I can't tell if she's a regular on the bus or not and I don't know if I'm going to see her again. I'm a jittery person and I seem to attract emotionally volatile people on public transit for some reason.
