Fun fact: just as the Chinese (and I think other asian cultures) utilize "rice"(their staple grain) as a synoym for a meal so in English we use the concept of a staple grain as a synoym for a meal: meal.
The use of "tea" for that meal remains a class signifier; my paternal grandmother used it, my parents did not (my mother, despite not being a native speaker, presumably is the one who eradicated it from my father's vocabulary), and yet I continue to say unwittingly say it occasionally though I now live in the USA. A vestigial Australianism in my case
It's definitely "non-U" in the UK, though that whole world is mostly gone.
