Here’s a related question for you Duke - one which Benway, Oz, or another British subject matter might be able to answer too.
Do most UK restaurants continuously brew coffee like they do here in the USA?
For those unfamiliar with this custom, most restaurants in the USA have a glass coffee pot at the ready. In fact, most restaurants have a setup for two pots sitting side by side so that a fresh pot can be brewing while the other pot is available to serve from. [This is clearly not the Starbucks method.]
