Drunken Mistake! Help!?

I have been flirting with this waiter (single!) who seems very interested in me every time i go into the bar/restaurant he works at. He is always very attentive toward me, hugs me, gives me free stuff, and gets a huge smile on his face when he sees me. I finally got the guts to give him my business card, and was very very drunk when I did it-I was under the impression that he wasn't very excited to get it (even though I think he was, it was just busy and there were people around) so I made some comments about how I thought he was rude and didn't think he seemed like he really wanted it . He said some smart *** comment and and so I demanded for my card back!!! i was really drunk, and I think they thoguht it was funny, but he gave it back eventually and I left. Does he think i'm crazy? What do I do now?
