If you just ask for ‘a coffee’ in a different European cities, what do you get? In Brussels the answer is simple – a long-ish espresso type coffee, with a slightly burnt edge, normally served with a biscuit (perhaps a Speculoos), a couple of sugars, and some cream. In France you would normally get the same sort of thing, probably shorter. Un caffé in Italy would be a straight espresso. In Sweden you would get a bryggkaffe, with a refill if you’re lucky. In the UK? Hard to say. In the past you might have been given an instant coffee if you just asked for ‘a coffee’, but with the Starbucks invasion times have changed, so I’m not sure what the UK standard is now.
