It is an established fact that Chacha never locks the door of his house when he steps out. However, Bini Chachi is seen locking the house on a couple of occasions in the comic series. Also, it is never revealed what Chacha Chaudhary does for a living. In certain stories, Chachi is shown complaining about Sabu's mammoth diet and how there is no food left in the house. How Chacha manages to earn bread and butter for the family, including Sabu and Raaket, is never revealed, but it is apparent that Chacha regularly gets rewards from the Police, Governement, other organisations and individuals for their help to the society.
