Tea in London

I believe tea with milk, with or without sugar, is the norm in England.

My father would say, "just enough milk to sweeten it a bit."  He'd always take tea that way, as would his mother.  That's what I knew as the English way.  So (realizing the better ones mentioned by others here are preferable when they can be found) is Tetley the best of the cheaper, grocery store brands?

More tea Vicar?
