You can learn about various techniques (for the better or worse) just by learning the terms:

You can for instance look up the term BHRR (Bait, Hook, Reel, Release). However, you can't think in such technical terms while you are out in the field. So in plain english it means that you ask the girl for small favors. "Can you watch my beer please?" and such. If she complies you reward her, most preferrable by using kino. Touch her shoulder and say "thank you", and then let go.
The longer you have known each other, the more you can ask of her, and the reward can be greater too. So you have to start small, really small, and the increase the investment. In the beginning, don't ask more from her than you would accept yourself from a stranger. If she has any manners, she will comply out of pure politeness.
