Re: Now I understand
For those of you too young to remember the alfresco dining experience in the UK before chains.
A cafe would have an urn of tea, containing a large number of tea bags, more boiling water would be added during the day.
As a child of the 80s I don't really remember before chains and growing up in Northern Ireland little dining was alfresco. However, the urn of tea description was definitely not accurate for that era, tea would be brought (as it still is in many independent places and hotels) in a one or two person pot with actual boiling water added to the appropriate number of teabags. A second pot of hot water with no teabags to allow topping up was not universal, but pretty common (otherwise a waitress or waiter would often stop by later to offer one). The chain experience is pretty universally hot (but not boiling) water poured into a cup and a miserable teabag on a string added (usually in that order).
In the 90's before Starbucks really took off in most of the UK, it was pretty common to be able to get espresso based drinks in nicer cafes, although most would have some kind of drip machine and while that might generally continue to boil the coffee after production it's not really a big problem during a busy period when it would come fresh, individual or two person cafetieres to the table were also not uncommon. Particularly noteable, and something that disappeared for a long time under the big coffee chains (and which has only really come back in independent shops, while chains offer a nod to it as an extra alongside vanilla syrup), there was often a choice of coffees, although in the Whittards sense of Kenya, Columbia, Brasil etc. (Particular memory of trying to persuade someone at university that this was actually different coffee in a way that cappuccino, latte, moka were not.)
