I've looked at Mark Manson- who says being vulnerable asking a girl out directly- I think you're pretty lets get coffee confidently is better than doing it indirectly which wastes time.
David D says this gives up power and you shouldn't do this because you are asking permission. What gives?
How do you ask a girl for coffee?
I always thought it was do you want to get coffee, or come get coffee with me (which is usually what I say)
