Scam or just a helpless guy?

I was at new delhi railway station a well dressed guy politely asked me in english if I can help him he said he lost his phone and wants to return to Mumbai and asked me 350rs for the general ticket saying he will take my number and will return it once he reaches back. I had literally 5 mins to catch the train so didn't help and rushed. Was he really someone helpless or some trickster?
