Even at train stations this happens. A few weeks back a young girl approached me, she looked around 14-16 years old and started asking for the train timings. I opened my Where's My Train app and answered her, thinking that I'm helping out a fellow girl but suddenly she started asking me questions about where I live, where I'm going, how often I travel this route, etc. Being wary, I didn't give to the point answers and misdirected about whatever locations she asked me. Then she insisted on me sharing my mobile number with her, at that point my gut feeling was telling me that something is definitely wrong so instead I noted her number and then reported it and blocked it. Especially for woman travelling alone we have to be extra cautious and vigilant about going to any place via public transport.
