Context really is everything, which is why I found your comment misleading. The topic of her post is not that a male hit on her anywhere in San Francisco. What she's talking about is the fact that some male(s) interpreted exchanging of business cards as "giving out a phone number" which can then be used for personal reasons, such as hitting on her. Furthermore, she finds herself facing an interesting dilemma: she feels she can't be "harsh", because they're a business contact.

It is an interesting topic, at least for me: I'm male, so I haven't had to go through a situation like that and I don't have a clue how I would respond to something like that if I were in her shoes. Had I heeded your summary without reading the blog, I would've missed a mildly interesting topic.
