Hi guys. Let me just state real quick, I am out of a long relationship but now i am looking to just get into the game. And btw, I never really had any game since apart from few long relationships there was even fewer amount girls i hooked up with and for those I could see from a moon that they were obviously interested. So I might say i am quite horrible in random chats with unknown women.
Back to the story. I went to the hairdresser, I have long hair so decided to shorten it quite a bit for this hot summer. I also decided I will practice my communication skills on a hairdresser if she isnt remarkably unattractive or way out of my age range. So I pick a random (

) saloon where I passed by before and recalled that maybe some cute girl was working there so I get in. And I was right. I also noticed she looked familiar, had no idea whiy.
There was a guy already taking a haircut. And after a pretty official "hi i want a haircut" i take a seat and wait for my turn. So as I sit there and they communicate I notice how talkative is she and that basically all hairdressers are like that because thats in their job description. And I also realized that because of that it will be horrible to distinguish if she is interested or just polite. But hey, practice is practice and I need one.
So, my turn. She comes up and I say: "I want a summer haircut!" She cracks a laugh right away since she noticed how long is my hair and how horrible it would be for me to take it down for me. Then simultaneously touches wrist of my hand (simpathetically i suppose) and says something to me what i forgot because i was too busy noticing that she kino escalated on me already.
Anyway, chat kept going on but laggy and insecurely on my part and all that way there were quite few comments on my side that reeked of clumsiness, negativity, etc. Half a way through haircut I figured out where I might've known her and it turned out to be true. She was my generation in elementary school but from the other class. And she was quite surprised that i remember that, so we found a bunch more to talk about although we never spoke single word to each other in school.
Anyway, after all that rollercoaster of clumsiness and the fact that i had no idea if she was interested (because of her profession) I failed to grow balls to ask her for a phone number.
So here are a few questions that bug me:
1. Was it bad of me to assume that I will have difficulties to detect IOIs because of her profession? Should I just completely disregard it and proceed as if I am flirting with anyone? What IOIs too look for from type of person that is just as easily conversing and connecting with everyone?
2. A job question. It always come and I don't know how to deal with it. You see, I play poker for living and when I tell them that the usual follow up is:"How much do you make?" or "Whats the most money that you made?" And then I feel uncomfortable to answer that and come up with bunch of inconclusive answers. Since i can often make in a month what most people i know (and most people in my country) dont make in a half year and thats not really something I want to be recognized for. Plus it attracts gold diggers
3. She would sometimes make a playful comment, like at the end of our session:"Hand me over that rubber band, right now!" in a commanding but playful voice. Was that an IOI stabbing me in the eye and I am too blind to see it?
4. She asked me if I was married/in relationship. Not sure if that was before we concluded we went to school together. (does it even matter?) IOI again? However then we started talking about past relationship, so I mentioned a 5 year long one I ended 2 weeks ago and she mentioned a 7 year long one that ended years ago. And she also mentioned something like that she is not that much into relationships any more??? And I have no idea what to make of all of this? (also i think i should've diverted the topic ASAP)
5. Did i fail miserably with no chance of recovery? I did mention at the end I might come in a month or two again to fix my hair again. I can also be a creep

and intrecept her after her work is over and chat her up. I should note that my interest is purely sex/fun unless proven to be a gf material and she is quite hot so I sure would like to take another crack at it.
Thnx for all input in advance. I hope it wasn't too long.
