working a shift at my side hustle, if cutie at work whose in my age range with whom I've had some good interactions with is there I'm going to ask her,

"Hey, can I message you on whats app sometime, would you be into hanging out sometime?" casual no big deal

If she says no, I'm not going to do anything different, will never ask again of course,

I want to convey that "you could say yes and I'll make my sales pitch, if your not interested thats cool, no pressure"

what do? Should I try to test the water a bit more, whats a good conversation we can have I have no clue how to talk to girls (i'm 30's shes late 20's)
