How far apart to stand
Stand about a metre behind the person at the counter and you are second in line, holder of rights, successor to the throne. Stand three metres behind them and you are a person loitering near a wall. Somewhere between those two positions runs a boundary that no one has ever measured and everyone can find: the distance at which standing becomes queuing.
The interval is a sentence with two clauses. It must be short enough to say I am with this queue and long enough to say I am not with this person — and both clauses are load-bearing. Drift too far back and the claim lapses: someone slides into the gap, and the queue, consulted silently, rules the entry legal. You had stopped paying rent on the space. Press too close and the other clause fails: the neck ahead of you stiffens, weight shifts, a half-step is taken that the queue's progress did not require. The anthropologist Edward Hall, who measured how far apart humans arrange themselves, would put the queue at the awkward frontier between his personal and social distances — closer than strangers stand, farther than companions do, which is exactly what a queue is: strangers who have agreed to be adjacent on schedule.
Some counters command a premium. At the ATM, the pharmacy, the bank teller, the standard interval roughly doubles, and the extra length is not courtesy but theatre — a public performance of being unable to see. The half-metre says I could not read your PIN from here, and it only works if it shows: discretion, to count, has to be legible from behind. Where the performance kept failing, management reached for paint. Please wait here for the next available teller is an admission, in signage, that an unwritten distance had to be written down.
The interval is also alive. When someone joins behind you, you will often take a small step forward that the queue did not grant — closing ranks, confirming membership, passing the new arrival's pressure up the line. Each person keeps their spacing against the one ahead, which is why a queue moves the way an accordion plays: the gap at the front travels backward through every body in turn. And when someone hovers at an unreadable radius, the whole instrument produces its one failure sound — sorry, are you in the queue? — the floor asking out loud what the distance was supposed to have said.
Once, recently, the interval became law. In 2020 the gap was set by decree at two metres and marked in tape on the floors of the world — the first time in the queue's long history that its load-bearing distance was published. The tape wore away unevenly, and here and there its ghost is still down there under the scuff marks: the one fossil ever left by a structure whose only building material is the space between its members.
