It happens but not that often. They try to start a talk, then wait for you to get their number that's how it happens to me.
The last time a girl did I was sitting in a tramway and two girls in front of me started to talk and laugh and I knew they gonna say something to me ( They looked at me the whole time and I know they did because I was looking through reflection in the window and saw them looking at my face while I was pretending to look at buildings on our road
). Finally one of them asked me the dumb question " In which station you are going to?" so I replied and she started to ask me about different stations like she wanted some help then we got to different subjects.
Some girls approached me in really weird way, seriously, it's just fucking embarassing for everyone. One time I was at a job interview and apparently a girl was there waiting with me too. I noticed her and kind of hated how the fuck she acts like she was a classy lady or something and she said " You are here for a job interview?" I said " Apparently" and gave her a nod. I have no game/swag but I never start conversations in such dumb ways.
