too strong?

Apparently I come on to women way too strong, a buddy of mine told me that I do one of two things I come in guns a blazing or I don't shoot at all. I got to thinking about that and I feel there must be some kind of happy medium ground where I do just enough. Last night I worked out with too of my friends and we decided to go to buffalo wild wings, we got this little waitress and I figured it was a good chance to practice breaking some balls. It takes her forty minutes to get my vodka and cranberry, of course we're in no hurry, but I look at her and say "so...what's the deal? you a rookie or something?" and she looks at me and says "oh my god you can tell?" and I say "well it kind of shows" and then with out missing a beet one of the guys I'm with looks at her and says "no, I don't think it shows at all" and I was thinking what the hell dude. So I keep breaking the girls balls every time she comes back, and my buddy keeps making a wuss out of himself. toward the end of the interaction with the girl I ask her if she has any of those cards to rate waitresses, and then she tells me they don't exist, and the wuss of the group says "lighten up dude, she's doing a good job" like I'm going to give a bad review and get her fired or something. So finely like two hours later we're getting our bills, I hand her my card but I hold on to it for an extra second and look her in the eye and say "you know, you should put your phone number on the back so you can take me someplace nice some time" she laughs and brings the bill back with no phone number.
