Summary:
The famous Mumbai dabbawallas are an essential part of Mumbai' s culture since 1890. They provide delivery service in Mumbai, India, picking up the home- made, fresh food, which the wife cooked, from the client' s house and delivering it to the downtown offices where the husbands work. The concept of the dabbawallas work only because of the mentality Indians have, valuing home made food. Also, the prevailing environment makes their services very valueable. As traffic and public transport in Mumbai is always very dense and it is a headache to transport something, the dabbawallas remain unchallenged in their field of expertize. They use a color code in order to deal with the illiteracy of the dabbawallas which make them so special. Moreover, it is mind-boggling that their error rate literally is zero and that this great accomplishment is achieved by illiteral people increasing their reputation dramatically.
