One big change I've noticed between growing up in a small town and now where I'm in my mid 40s in a big metro city in India is increased "transactional" nature of interactions of my daily life.

There used to be local vendors as you describe (what comes to mind is a local shop, an ice cream van, milk man, a fizzy drinks vendor, a butcher/baker), but they've all been replaced by economies of scale (supermarkets and now online).
