At least instant tea seems to mostly have gone away! I never quite understood the point of that; while making proper coffee does require special equipment, it is quite possible to make a decent cup of tea straight in the drinking container...

Not being a coffee drinker myself, I usually keep some instant 'coffee' in the house for recipes that require coffee and to offer to guests (notably Mum, who as I mentioned does like it). I did usually offer it to my friend K paraphrasing Douglas Adams as "a substance almost, but not quite, entirely unlike coffee".
