I stumbled on this British WWII propaganda film. Were the troops complaining that the tea maids weren’t making good tea? It seems like it if they needed to teach people how to make tea en masse. But it ends with the 6 Golden Rules for Making Tea, which if more people knew today, it would be easier to find a well-brewed tea.
I want the “Tea Revives the World” poster that’s hanging behind the male instructor.
