The British introduced the tradition of
"Tiffin" in India. Nowhere in India, except
Mumbai (formerly Bombay), has it taken such a strong hold.
From this habit of taking a snack-break at lunchtime,
evolved the institution called "the Dubba-wallas".
This is an organisation of lunch box carriers, absolutely,
unique to Mumbai. The office / factory workers of Mumbai
have to leave their homes very early in the morning to
get to work on time. After they have left, their wives
/ mothers / sisters cook the meal and pack the lunch box
(dubba). The dubbawalla arrives at the appointed time,
collects the dubba and through a relay system, ensures
that the right person gets the right dubba. After lunchtime
the whole process is reversed and the dubba arrives back
at the starting point.

The only identification marks on these dubbas are some
coded scribbles put there by the dubba-walla organisation.
Since there are literally, hundreds and thousands of dubbas
being transported every day, to and fro, how the right
dubbas reach their rightful owners in the workplaces and
back again to the right homes, is nothing short of astounding.
On the local trains, these dubba-wallas have specially
reserved compartments for safe transportation of this
valuable cargo. An organisation similar to this does not
exist anywhere else in India or the world.
