I guess those instructions would be written on the back of a box of Earl Grey tea and hence why I've never seen them. ;-)
FWIW, 'we' (the Mrs and I) generally drink the cheapest decaff we can find and made in the mug (we don't actually have a teapot or cafetiere).
In the same way I've never liked bitter or 'real ale', preferring any old cold lager because I mainly drink for 'refreshment', not taste.
I used to have tea and coffee (I prefer instant coffee over any of the alternatives) with two sugars and now I have no sugar, both taste different anyway. In fact, in an experiment around not consuming any 'dairy', I can (and often do) equally drink either black with little issue.
But then I've never really been interested in food or drink as a major part of my life(style?) or make it hobby or interest. ;-)
Whilst that may make me a heathen to some, it does release me from many of those social chains and give allow much more time for actually 'doing stuff'. ;-)
