I think that if your are counting on $$$, you're in trouble. Girls here are very proud, you know, they will never tell you that money is important, but it is very good thing when you have it. You should just act normal, be a normal guy, make jokes with them, act like you are not interested in relationship, only friendship, and through that, you will notice if she is interested in you or not. And don't force anything, because then you will never have a chance to try. The thing you sad about alcohol...I don't know where have you spent your time and with who, but 90% of the girls here are drinking alcohol. Actually, I don't know any girl who doesn't drink alcohol I wish you a good luck here, first of all, enjoy this beautiful nature and relax, and when te night falls...Always wear protection
