I'm not a teetotaler, I'm not British, but I always get at least one tea in lounges. On Short haul I stopped some years ago after a very foul tea, boiling hot, tasting "off" and with not enough sugar (I was embarrassed to ask again for more).
So, on SH my tea total is usually zero. It also helps that most of them are in Y and I'm not going to order anything from a menu.
