In the 1960s, on the street where I lived, i.e. Cheng Yan Place, I remembered very vividly that every afternoon at more or less a fixed time, an Indian man would traverse the street on-foot from the Queen Street side towards Victoria Street (please see map in post before the last one). Always with him were his 2 cows, one brown and the other white. He was a street dairy (also daily) seller.
If you wanted to buy some milk, he would stoop down and milk it straight from the cow for you. He would then bottle the milk into a glass bottle right in front of your eyes. Now how could you get milk fresher than that, brown cow?
The hygiene practices of this Indian man were questionable. Why, I didn't think he ever bothered to clean up the bovine poo that the 2 cows left on the street every now and then. Even if he did, I didn't think that he bothered to wash his hands after that. That's why I never bought any milk from him, haha.
