As a man dressed in a smart kurta and jacket walks by, I ask a bystander if he recognises the figure. Awed, he mumbles in a barely audible voice, "Modiji".
There was another time not too long ago when people at a political rally spotted the same person in a car and started following him around, chanting "Modi… Modi… hum tumhare saath hain!" The security personnel had a tough time protecting him from the crowd.
That man, of course, is not Narendra Modi, the Bharatiya Janata Party's nominee for prime minister, but he looks like the Gujarat chief minister, and talks like him too. Meet Vikas Mahante, a 52-year-old from Mumbai's Malad locality.
The real Modi, hard-pressed for time addressing rally after rally across the country, could well turn to this Mumbaikar for help, for there is little to separate the two in appearance.
As I arrive at the residence of the Modi doppleganger, he is just wrapping up another interview.
Mahante has been interviewed by India News, Zee News, Sahara Samay and News 24. The anchors question him about the changes in his life brought about by being a Modi lookalike.
They also ask him about security problems. Mahante tells his interviewers of how his family - mother, wife and two sons - was initially apprehensive about him campaigning when people pelted stones at him at a function in Dharavi in his initial days as a Modi stand-in.
But seeing the response of the people now, he feels, they have come around. He faces no security problem either.
