Using your intuition when approaching is great.
This time I was approached at the time I wanted to approach a woman who was strongly radiating something. She was seated close to a bar. The set was a 2-set and the girl invited me like this: "Come here.". When I arrived she started to laugh and she said 'We have just eaten". I was about to start talking but the lighting was poor and I could not see really well. I spontaneously decided to leave.
After a week or so, I found out by mistake that she was working in a shop. She always stands outside waiting for the customers to come in. My mindset always prevents me to approach girls at their workplace but this time I had no other option. Once I was walking outside her workplace and she delivered the Universal Opener.
I said "Hi!" and went on walking. I always have problems to stop to talk to girls, it just doesn't feel natural.
My third chance was another day that I was feeling down while I was alone in a cafe. I was seating on a table and I was facing the girl's shop. I accidentally found out that she was there working again. She was talking to coworker and they both started to stare at me. Again something was happening perhaps and I could take action. She then started using her mobile phone to shoot some shelfies. She was taking a lot of shelfies so as to get people's attention.
After half an hour I decided to get up and leave. I walked to the cashier's and I was waiting there in order to pay. All of the sudden the girl entered the building I was in and she grabbed a bottle of water off the fridge. She came really close to me and she was standing there. I sensed that she was doing something on purpose. Again AA, I did nothing.
