You have always been able to buy excellent coffee in the U.K. you just need to go to an Italian owned independent deli. I was drinking what are now marketed as flat whites 30 years ago as espresso con leche, coffee with a little hot milk, it's served across Europe as pretty much the standard coffee, just in England we imported the American habit of bucket sized drinks for some reason. I usually drink double espresso these days [/quote]
I blame Starbucks for the milky bucket approach. It's a shame we didn't adopt the Italian model for coffee instead. Costa may claim Italian roots but their coffee is mediocre at best in my experience. Caffe Nero has an Italian name but its coffee isn't great either. I never go to Starbucks because of their tax avoidance history so can't comment on their coffee, but all that stuff about sickly syrups being added to coffee doesn't give me confidence it would be any good.
Pre Starbucks, coffee in cafes and restaurants in the UK was even worse, more often than not, for my taste. Far too often it was weak or bitter and if you had it with hot milk the milk had been boiled and left bits of skin in the coffee. 
I don't want a super milky drink with minimal coffee flavour. I always choose a flat white in the hope of getting something pretty strong but also milky and hot. In some places they say they do latte, flat white and cappuccino, but in practice they all look and taste the same, lukewarm, weak (often managing to be weak and bitter at the same time
) and disappointing. In a place like that I'd probably switch to Americano or filter coffee as it would be marginally better.
I hardly ever drink tea outside my own home as it is just so disappointing. I love tea but it has to be just right, and I always make it in a teapot and keep it hot with a tea cosy. What I get elsewhere is a teabag dunked in a cup of hot water, not necessarily even boiling!
Where a teapot is provided it's always too small and there's no hot water to top the pot up to stop the tea becoming undrinkably strong.
And don't get me started on the abomination of providing UHT milk for tea.
