I'm a little stuck... Click here to teach me more about this clue!

'afternoon refreshment?' is the definition.
(I've seen this in another clue)

I don't understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for tea that I've seen before include "Tisane" , "Popular drink" , "Eg, gunpowder, pekoe" , "Assam or Darjeeling, for example" , "Afternoon meal (3)" .)

I've seen this clue in the Evening Standard.
