Tonight we went to a local pub in my city. There was a cute waitress, and we started teasing her, asking her her opinion in our conversations and telling her that it was a pity that she couldn't join us for a drink. She seemed pretty receptive and she often teased us too. When we were getting out I just said: " What can we do so next time you can join us for a drink?"...expecting her to say something like here is my number or something, but she just said: "we will probably meet again some day".....a totally blow off. I don't konw what realy happened...What did I do wrong, or what do you have to do in these cases??
