MUMBAI, India — The famed dabbawalas of Mumbai are celebrating the birth of the Duke and Duchess of Cambridge’s baby with the Indian tradition of passing out sweets.

Thousands of dabbawalas each day pick up lunches at workers’ homes and deliver the lunches to them at their offices. They have been hailed for their efficiency and Prince Charles visited them a decade ago, creating a connection with the men.

On Tuesday, the white hat-clad men welcomed the birth of his grandson.

“Prince Charles has become a grandfather. He had come to Mumbai as a friend and made us famous. We are very happy for him so we are distributing sweets to express our happiness,” said Bhau Saheb Karwande, a dabbawala.
