How do the logistics of this work? Did he bring one cow or several? Or is one cow enough to cover the sales of the day? Or is there a stash of cows nearby and he exchanges them? Are they on different milking time rhythms? So many questions. Can you elaborate a little please?

This is still prevalent in small Indian towns and villages. There is a stash of cows nearby and he chooses a cow, brings it to the residence, you provide your wide-container/pail and he milks the cow at your veranda. Milk is served at only one time - early morning.

You still need to boil the milk for several minutes to kill all bacteria.

Today I learned...

Presumably those cows are treated quite well too. I've been stuck in cow related traffic jams before and I've seen how well they're regarded, so I can only assume milk cows are taken very good care of. Injections seem like they would be off the table because they're both not free and inflict pain. That means there are probably calves involved. Any idea what happens to them?

Not so I'm afraid. Antibiotic use for ag use is exploding in the developing world and that includes India.
