Hey fellas, so I met this waitress tonight, and before I left the restaurant I asked for her and said "hey (name) you're kind of cute and I would like to get to know you more,may I get your number" she gave it to me, and now we have been talking. here is the conversation thus far (yes I wear a kilt and it is epic):
me: hey (name), it's Me the guy from tonight in the awesome kilt.
her: haha hey. yeah it was
me: what evening are you usually available?
her: it depends
me Depends on what?
her: it switches up a lot
me: ah okay, do you know your schedule for this week?
her: well I have school and work I know that

What the hell do I say next or which direction do I go to move things along?

Should I say "Alright, well I want to see you sometime. When would work?"

ended up saying "Alright, well I want to take you out. When are you free?"

This case is now closed. I found out she has a boyfriend...

If that conversation went exactly as you describe it here she wasn't interested from the jump and you need to learn to read that.

She prob doesn't have a boyfriend.

Girls tell guys they have boyfriends so they'll stop hitting on them.
