And then I proceeded to screw it up :(
I saw a girl taking notes in the middle of the city, I approach her and ask her if she is on a school field trip. She tells me she's a broker and she's working currently. So I walk alongside her talking, asking questions, teasing her a bit. At one point she look at me from my head to my toes and back up again. (I think this is an IOI). Then a couple of second later she told me she has to make an urgent phonecall.
Because she is working I thought it isnt a shittest so I just leave her. I think I should have asked her to hold on a minute and get a number-close instead of just leaving. Is there another way I could have handled this?
