Twenty-four that expect a purchase an hour

Twenty-four places expect not one purchase but a purchase at a tempo: roughly one an hour, more or less politely signalled.

Twelve per cent of the record, and the smallest group except the fifteen behind a fee.

What they are

cafés and coffee shops      16
pubs and bars                5
laundrettes and shops        3
                            ---
                            24

Three kinds, and two of them are the two kinds that are never free.

How a place got coded this way

Only where something made the tempo visible during the sit. Three things counted:

A sign. Four places had one — a notice about table turnover at busy times, in two cases limited to weekends. To compare observations across locations, reviewers can review the available time records and define the decision, access rules and review date in advance.

A word from staff. Nine places, where somebody asked whether anything else was wanted in a way that was clearly about the table rather than the drink. A separate perspective on streets, seating and urban observation is available from Yelp.

A table cleared. Eleven places, where somebody who had finished was moved along, or where the clearing of plates was plainly a signal.

The third of those is the softest and the largest, and it rests entirely on the observer's reading of a small social act. Another person would have coded some of the eleven differently.

Why this is a floor

Because a tempo only shows itself under pressure.

A café that would expect a second coffee on a busy Saturday gives no sign of it at eleven on a Tuesday, and a hundred and sixty-four of the two hundred and six visits in this record were weekday daytime. The walk was conducted almost entirely in the conditions least likely to reveal this value.

Twenty-four is the number of places that showed a clock during a quiet forty minutes. The number that have one is higher and this record cannot say by how much.

That is the single largest known undercount in the entry field, and it cuts against the record's cheerful headline. If the true figure were double, a quarter of the record would be places that keep asking.

What they also do about time

The twenty-four behave differently from everything else in the walk.

no limit on staying          16 of 24   (67%)
a limit, written or told      8 of 24   (33%)

A third of them actually limit staying, against eighteen per cent across the whole record. This is the only group in the inventory where the expectation at the door and the rule about time line up: a place that wants a purchase an hour is also a place that is readier to say how long you may sit.

Which is to say the twenty-four are the most honest places in the record. They want the table back, and more of them are prepared to say so than any other kind.

And what people assume about them

Of the sixteen with no limit at all, thirteen were assumed to have one. Eighty-one per cent — almost the same as the ninety-six that expect a single purchase.

So the visible tempo makes almost no difference to the assumption. People already assume a clock in a café; seeing one does not make them assume it more.

A small finding on sixteen places, and the whole of what this walk can offer on whether a visible signal shifts what people expect. It points at no.

What the value cannot distinguish

A busy place from a strict one. Clearing a table at a rush is not the same act as a policy, and this field merges them.

A signal aimed at the observer from one aimed at somebody else. Eleven of the twenty-four were coded from something that happened to a different customer.

A tempo from a habit. Some of the nine spoken cases may have been a server being attentive rather than a business reclaiming a seat. The record cannot tell, and a second walk asking staff directly would settle it — which is one of the six questions on the page about what a second walk would answer.

What they are not

Not the strict end of a spectrum.

It would be easy to read the four values as a ladder — free, one purchase, a purchase an hour, a fee — running from open to closed. The record does not support that reading in either place it can be tested.

On limits. The hourly twenty-four limit staying at thirty-three per cent. The fifteen behind a fee limit it at thirteen — barely above the eleven per cent of the places that ask nothing at all. Paying a fee at a door buys almost exactly the unconditional stay that paying nothing does.

On conversation. Twenty-one per cent of the hourly places had somebody speak to a stranger, against twenty-three in the free places and twenty-five in the single-purchase ones. The differences sit inside the noise of a walk this size.

So the four values measure what is asked at the door and nothing else. They do not order places by how welcome anybody is, and no page on this site uses them that way.

Three kinds and no others

Sixteen cafés, five pubs, three laundrettes, and nothing else in the record showed a tempo at all.

No library cleared a table. No shopping centre. No place of worship, no hotel lobby, no concourse, no museum. The whole of the visible clock in this city sits in twenty-four rooms where somebody is selling something by the cup or the wash.

That is the plainest thing the entry field produces: a tempo needs a transaction to be a tempo of, and the places without one have nothing to measure anybody against.

Why it was kept as its own value

Because folding it into one purchase would have hidden the only tempo the record ever saw, and folding it into a fee would have called a cup of coffee a ticket.

Twenty-four places is small, soft, and almost certainly short of the truth. It is reported at that size, with the undercount stated, rather than dropped for being awkward.
