Sounds like maybe she was drunk...how humiliating for the girl though for that to happen in a place with so many people.

And how awful you must have felt I would have freaked, especially with it getting on your shoe ah! I think if it wasn't NYC streets, I would have walked home in my socks haha.

Good job for not totally freaking out and just "casually" moving to another car.

You should be okay. I know its easy to say to try and not think about it, but thinking about it constantly will make you think you are sick. Just as long as you didn't touch it you should be fine. I too think she may have been drunk. It's New York....there are MANY reasons why somebody would've gotten sick.

Was she alone or with somebody?
