Indian shop vendor working during the day.
An Indian man is working in his shop during the day.
Just because an Indian shop vendor is working during the day doesn't mean that the vendor is a man.  The Indian shop vendor could have been a man or woman, but the second sentence reveled that the vendor was a man.
