I know I was vague with my previous post.

Here's the deal:

Let's say you were a girl and a guy you met at work asked you out. Unfortunately, you aren't interested. He gives you his phone number in case you want to hang out. First question, would you even call him just to be polite?

Second, after a few weeks, you and him sat down together (outside of work) and tells you he likes you a lot. Now how would you handle that? Assuming you're going to say, "I like you as a friend..." Would you give your phone number voluntarily (maybe to be nice?)
What would a guy think of this (giving out your phone number after telling him you are not attracted to him).

I hope this would suffice for now.
