Prime Minister Narendra Modi on Friday said that even after the four and half years of his government, the Congress party has still not been able to digest the fact that how a “Chaiwala” (tea seller) became the PM of India. Addressing a rally in poll-bound Chhattisgarh’s Ambikapur, Modi said, “It has been nearly four and a half years and these people have still not come to the terms that I am the PM. They are still crying, how can a 'Chaiwala' become PM?”
