Often I have have purchased a much-needed cuppa only to lift the lid and discover a pale milky concoction with a teabag festering at the bottom; the tea having been made by adding the milk (often way too much of it for my liking) almost immediately after the hot water, therefore making the tea-brewing process redundant. It's barely possible to get more tea flavour out of a bag once the milk has been added. You wouldn't add milk into a teapot, so why put it in the cup?
And for this service they charge at least £1.50. It's so disappointing. And a rip off to boot!
To make tea – add boiling water to tea bag, let it rest/brew or squish the bag a bit, and then add milk if so desired. Satisfyingly simple!
