I was thinking of a good way to approach a person on a treadmill in campus gym. should work on the street too. please give me feedback and advice on delivery

you look like you are worth a coffee? [HB: i have a bf, don't have time, or blah-blah]

you look nice and everything but I need get to know a person first before I decide if I'm romantically interested.
And how do you know if we don't have common interests, complementary talents or some kind of synergy?
there is more to life then work, gym and going out. in the end the life is built out of unforgettable experiences.

(first time here, first post, and need to take a break from work. i did read a bunch of pua books)
