Is it normal to pickup women at random places?

Hey, I always find unspoken rules between men/women very interesting ....
I first congratulate you by having the BALLS for approaching a girl u didn't previously knew, you are already braver than 95%% of men that don't do that only for fear of rejection....
I think that in that situations is important the timing, maybe you came a little to hard at her at a place where her defences where low (unlike in a singles bar or disco where he dressed her best, spent a lot of time with the makeup and feels very powerful and expects all men to approach her). I think that you shouldn't stop to approach girls in random places, just don't go directly for her phone or a date and instead try get her opinion on something related to the place u are (grocery: opinion about clothes soap...street: a direction at some known place...gym: if she knows the guy that recommends the workout routines and where can you find it), and after you get her attention in a harmless level, try to change the subject into another topic. If the interaction developed quite smooth, then ask casually for her phone. If a casual conversation didn't develop, just say goodbye politely as if the info you requested was all u where looking for. Don't take too personally this rejection and this hurtful comment on her profile, women already have enough things to worry about, maybe she was much more insecure than you and her lack of confidence made her deprived her for the chance to meet you.
So bottom line, congrats, u are very brave and don't let this obstacles stand in your way of finding the kind of women that you want and deserve.
Bye
