I don’t really know if this is new or not. I’ve never noticed it before.
While exploring a section of Trinidad de Cuba that I was not that familiar with, I noticed people lined up to buy whole milk. They stood in line with plastic or glass bottles of all sizes and shapes. The man behind the counter would dip his large cup into an open barrel and funnel the cold milk into whatever container the customers presented.
It did not look very sanitary, but the people seemed happy that milk was at least available on this day.
