I've never seen instant tea -- I don't think it really took on in the UK. The tea bag in mug method is pretty easy, even for a lazy tea-maker like me.

I have made instant for the builders; I don't think they liked it when I made them espresso! And my sister-in-law much prefers cafetiere coffee; she's very polite but she dilutes my espresso about 50:50 with water then adds a lot of milk. I can't recall when I last drank instant myself; more than 25 years ago I think!
