It’s Britain. The majority of the people there might actually put a cultural cornerstone like tea on a higher moral pedestal than your average adult liberals put state sanctioned ridiculous restrictions on children on. Anywhere else, you could attempt that, and people would laugh, and teenagers would protest, but ultimately no massive resistance would take place if laughing it out didn’t work. Because when authoritarian and pointless nonsense only affects children, no one actually sees it as a fundamental violation of freedoms and civil liberties. But in the UK, people might actually do something if the government tried to restrict who’s allowed to buy, brew, and drink tea. Because Brits love their tea and see British tea stereotypes as a Valued Cultural Institution.
