Culture shocks are not uncommon to Indians when they travel abroad. These shocks are experienced even more frequently and regularly by people travelling from one part of the country to another.

Delhi is a city that has assimilated people from all over and nobody in particular lays claim to it unlike other Indian metropolises.
