As a Briton, I'm afraid that I'm ignorant of the actual meaning of the
term High Tea (tho' I have heard the term).
As a Northerner, the sausage and chips (etc) assembly I might well call
'tea'.
As in, ' what're we having for tea? '

To which the reply would be,
' This splendid commemorative green pu-erh cake, my dear fellow. '
