This is from "Down and out in Paris and London" by G. Orwell:
"There were murmurs of agreement. Evidently the tramps were not grateful for their tea. And yet it was excellent tea, as different from coffee-shop tea as good Bordeaux is from the muck called colonial claret, and we were all glad of it. I am sure too that it was given in a good spirit, without any intention of humiliating us; so in fairness we ought to have been grateful--still, we were not."
This is a passage on how he and other tramps had to pray for half an hour in a mission in order to get a free cup of tea and two buns. Orwell also wrote an essay on tea brewing, although I don't agree with some of his ideas there.
