LOW STAKES. HIGH CHAOS.

Five flatmates. One dinner. Zero Michelin stars.

The guy who burns toast announces a three-course dinner. Naturally, the flat opens a market on which course survives.

Ollie has two reliable meals. One is toast. The other is toast, but later. So when he announces a three-course dinner for the flat, everyone puts their phone down.

“From scratch?” asks Jess. “Define scratch,” says Ollie. Excellent. We have a market.

The rules are stricter than the dress code.

They agree on a question: how many courses will Ollie serve on time, made by him, that the group judges edible? Zero, one, two or all three. They define “on time” before dinner and agree how the tasting vote works. Dietary needs are checked; anything unsafe stays off the table.

The judge is Sam, who cannot cook either but owns a clipboard. In a flat of six, this passes for institutional authority.

“The smoke alarm
is not a timer, bro.”

Jess, offering constructive feedback.

The feed develops a strong garlic note.

Ollie posts a shopping haul. Someone spots a suspiciously professional dessert box in the background. He says it belongs to a neighbour. The neighbour, invited to follow the bet, replies “no it doesn’t.” The backing for three successful courses takes a reputational hit.

Then a genuinely good soup appears. Confidence recovers. The whole point is in the updates: everyone can follow why the group is reconsidering, instead of remembering only the loudest prediction.

Two courses. One tactical retreat.

The soup is good. The main is late enough to trigger a rules consultation, but just within the agreed cutoff. The homemade dessert looks like a geological event. Ollie concedes it before anyone needs to taste it.

Sam records two qualifying courses and calls the result. The actual dessert comes from the very real box, outside the competition. Nobody minds. The judge’s clipboard has somehow acquired a bow tie.

The washing-up is not a financial instrument.

The agreed favours become tabs. The person who promised the washing-up does it, then the tab gets settled. No money changes hands through Conjectal; it simply keeps the claim, the updates, the result and the follow-through in one place.

Next month, Jess says she could host a better dinner. Ollie asks whether she would like to put that in writing. The flat has accidentally invented a supper club with considerably more trash talk.

Small stakes. A shared evening. An absolutely unnecessary clipboard. That is our kind of market.
