Ok, put yourself in this scenario...
You ask a girl you're interested in if she wants to grab some lunch with you the following day. She says yes and gives you her number and you tell her that you'll call her tomorrow to meet somewhere. And during the lunch, you plan to ask her on a real date.
Does that sound good or would you have done something different??
And what would you do next??
I'm not an idiot, I'm just trying new formulas...
Failure one, asking.
Failure two, not having a plan.
Failure three, not thinking it was a real date.
How'd it work out?
