Cafés & Coffee
Coffee Is A Unit Of Time, Not A Drink
Here a coffee marks an interval rather than satisfying a thirst, which is why it is small, fast, drunk standing and offered at moments that have nothing to do with wanting caffeine.

A coffee here is frequently a way of marking time rather than a drink someone wanted. Understanding that explains the size of the cup, the speed of the service and when it is offered.
The cup is sized for an interval
A small strong coffee takes a couple of minutes to drink. That is the natural length of a pause between two other things, and the cup is scaled to fit it.
A large drink implies sitting for half an hour, which is a different social act. The small cup lets someone stop without committing to staying.
This is why the default is small rather than because of any preference for intensity. The volume is a decision about time, and the strength follows from it.
It punctuates the working day
Work here is broken by short coffee stops rather than by long breaks, and those stops are how people mark the transition from one task to the next.
Because the interval is short, the café must be close and the service immediate. A five-minute queue destroys the function entirely, which is why counters are worked so fast.
It also explains the density of cafés. A neighbourhood needs one within a very short walk of everywhere, because the walk is part of the two-minute budget.
It is the standard offer in almost any encounter
Proposing a coffee is the lowest-commitment invitation available. It costs little, takes little time and can be refused or accepted without either party reading much into it.
That makes it the default for a first meeting, an awkward conversation, a small piece of business or the moment two people meet on the street with nothing arranged.
The drink is close to incidental in these cases. What is being proposed is a bounded, cheap, public interval of shared time, and coffee is the vehicle for it.
It closes a meal rather than accompanying one
Coffee arrives at the end, after the plates go and usually after any sweet. It signals that the meal has finished and that the table is now conversation rather than eating.
Anyone who needs to leave can go at that point without rudeness, and anyone staying has an obvious reason to remain seated. The cup does the social work.
Which is why it is drunk quickly even after a long lunch. It is not a lingering drink; it is the marker that the lingering phase has begun.
What this means for a visitor
Expecting a large drink to sit with is the mismatch that catches people out. The room is built for turnover, and a long occupancy is not what the price supports.
The adjustment is to have more coffees rather than bigger ones, spread across the day at the points where a pause would happen anyway.
Do that and the whole rhythm of the city becomes easier to follow, because you are moving through it on the same intervals as everyone else.
Questions readers ask
Does robusta give a stronger caffeine hit?
Per gram, yes, roughly double. Whether you notice it depends far more on how much coffee is in the cup and how many cups you have had.
Is there a third species?
Several exist commercially at small scale, including liberica and excelsa, mostly in Southeast Asia. They are rare outside their growing regions.
