How Coca Cola, Pepsi etc mean different things to different people

The large 2 Litre & 1.5 Litre bottles of Coca Cola,  Pepsi etc, are very popular among the migrant worker population here. While they buy tetrapacks & bottles of cheap liquor, it was a surprise to me, when I saw the large bottles of sugary soft drinks, they buy


In the labour camps they live in,  there are no bathrooms or lavatories,  or the numbers are less. 

So,  early morning groups of these people including women and children, walk into the empty plots and Eucalyptus plantations, with these large distinctive bottles, filled with water. Once their business is done,  they return with these empty bottles 

Nowadays, when I see these bottles at the bakeries and supermarkets,  I get a mental picture of these people,  with their water filled bottles.
