As a photographers we take our opportunities where we can and in India those opportunities are plentiful. Many shops and businesses are open to the street which has a number of benefits. The main one I suppose is access and the consequent lack of privacy. People working in these businesses are a part of the hurly burly of street life and are used to the potential for interaction with others on the street. The other benefit is that daylight streams into the premises which certainly helps to make the photography easier and more interesting.
