Is this a good way to talk to girls?

That is soo sweeet! I would half-way fall in love with a guy if the first think he said to me was "pardon me, but I think you are very pretty"--even if he wasn't my "type" look-wise or anything. There aren't enough guys like you. But maybe she might not like coke. Say something else. Like..."pardon me, I think you're really pretty. If you don't give me a chance to chat with you, you might break my heart." I think saying she's pretty from the get-go is a good plan since girls already know usually the only reason a guy will approach them/hit on them is because of their looks anyways. Best to be honest.
