On movies/TV shows, so often a character will go into a kitchen and help themselves to a cafetiere coffee that someone else has made or looks as though it's been sat around for a while. Is my £15 Dunelm cafetiere a dudd because the coffee in it cools as quickly as if it was in a cup and unless it's drank quickly after making, it's cold.
Obviously I know TV/movies aren't real but it's the implication that this is a normal thing and the coffee would still be warm.
Am I missing a trick?
