here's an example of the "Yes girl" I approached the other day:
Me: "Ha, random, but always cool to meet marathon runners! Jk
Enjoy your coffee. You're very pretty
-My name
Her: Hey [my name]! Sorry for the late reply! Hope you enjoyed your nap haha
Me: "Omg, I did! I needed it. Hope you enjoyed your cofee. Will you be bouncing off the walls for the rest of the night now? ;P"
Her: Tbh, that place didn't serve coffee
so i'm having coffee now. I might stay up all night
Me: Hm, I'd love to join a pretty girl like you for cofee tonight, but unfortunately I have plans already! 
Me: Are you a fan of beer/wine?
Her: Haha I'm actually with my friends too
Her: Tbh, beer haha
Me: Nice! Perhaps next week we can grab a drink in midtwon? I'll shoot you an invite soon if you're interested
Her: Sure! what abt Wednesday next week after work??
Me: That could work
I'll shoot you a text soon about the details... in the meantime, GL on the cofee hangover
Her: perfect! Have a great wknd and talk to you next week!
This was all in one day. The main thing is I knew she was interested via the approach, and in her texting she seemed excited (she's investing and putting forth effort, which uninterested girls don't put much effort in), she's asking questions (investing), she offered a day for the date on her own accord (a good sign), she's using forms of emojis (another form of caring/investing, which uninterested girls don't care to do usually), she's also responsive and within respectable time limits (i'm not waiting for a day or longer to get a text back, which is a bad sign).
My first text is a slight tease to remind her of who i am and the conversation. I then clearly state my intent by saying she's very pretty (no friend-to-friend date projections going on here!). I get a little back and forth conversation so I don't jump straight into the date invite. She mentions she didn't have coffee but yet she might stay up all night (saturday), which you can take that she's open for a possible date that night or meet up (possibly). I told her I'd love "to join a pretty girl like you" but I have plans already, so i'm stating that this is no friend shit. I then probe her from the agreed coffee date to a bar date as it's more sexual venue when i ask if she's a fan of beer/wine. Great sign when she says she likes beer enthusiastically. I then do the bar date invite. She agrees by suggesting a day herself (huge sign of interest). I don't have any particular bar in mind yet, and also Wednsday is like 4 days away, so I tell her I'll shoot her a text about the details soon. Then I don't text her again until I have the date and logistics set up in my plan. I don't text her in-between those two days, not once. It would look needy and it's completely unnecessary and would make me look needy af
