I'd be interested in suggestions for tweaking my stack to ensure a higher chance of a non-flake/getting the girl out.

I was thinking of closing with this:

"Alright, well I better go meet up with Chris, I’ll tell him what you said... You seem pretty cool though, I like your energy, you have a good vibe. I’d love to see you later for a cup of coffee. What do you say... Awesome, let’s trade numbers and I’ll give you a shout." (Input digits)

This would put me out of the fun friendy guy camp into romantic/possible sexual prospect camp. To get a number then a non-response flake after this would be rude.

Interested in feedback.
