Alright guys

this is my first time that I used things that I learned regarding picking-up women.
Here is the story:
I went out with a friend who still reads "the Game" book by Neil Strauss and we ended up at a pub.
We entered the pub and sat on a table and I saw the waiter (she was an

and I thought that I could at least open her and try to talk to her and see how it goes.
She comes to us, gives us the drink menu. We didn't say anything.
She comes back and asks us what we want. We ordered 2 beers and just before she left I opened her with "hey, I need a female opinion on something: Who lies more? Men or Women"
She said "both, in my opinion there isn't a difference between men and women except for the genital part"
I asked her "alright but how do you know that both are equal? Personal experience or what?"
She said "yeah something like that. Men say about women that we gossip more but instead they are the ones who gossip girls more"
I replied: "what? no way, there's no such thing!"
And then she went to get us the drinks. When she came back she started talk more (my friend was starting to talk to her aswell and ask her questions)
We fluffed around the gossip talk and then I moved to something else, another opener (I know... but I had to continue conversation with something else. The talking about gossip was getting boring for me)
I used the jealous girlfriend opener that Style describing in his book.
Again we fluffed around and she was smiling and wasn't leaving the table, so apparently we were interesting. She asked us what was our age and we deflicted the answer by asking her age (which was 24) and she didn't ask us again our age. So I thought I'd leave it like that, so we'll be more mysterious.
And then it came, the moment I got blocked. We were talking about why girls always like older men. And she said that she only dates guys older than her and that her bf is older than her. 3-4 years older and she was 24..
So we tried to crack her and deal with this bs about older men and she constantly said "no no no" when asking if she would date younger men. We went on every door to proove her wrong that older men aren't always more mature than younger ones and so on..
And when she insisted about that crap I ran empty on lines and my strategy was out the window...
Doing so, eventually my friend stopped trying to make her change her mind about younger men and we both ran empty. And she walked away saying "ill be right back if you guys want to ask me more stuff"
That line gave me the impression that she thought about our conversation more of an interrogatory...
We finished our drinks and when we went to pay her I had some strategy build up in my head but it didn't work. We gave her the money and I said "i'm sorry i didn't catch your name"
She said her name and then I said "well it was a pleasure of meeting you, by the way, I'm Thaz and this is my friend Nova"
And we left.
How's that for a first attempt?
Also feel free to criticise and tell me what should I have done in order to get her interested?
(I know it's a hired gun and we didn't use negs but she looked like if we negged her she'd leave the table)
