The Publican Who Runs the Whole Service

The lesson

Aunty Mei calls at 6

It is 6 in the morning, and the phone rings before the fire is lit. Aunty Mei, from the shophouse opposite, has a request. Her son’s birthday party is tonight: 12 bowls of stew, to be collected, by 7. I write 1 line on the order board, and I walk away, back to my carrots. I can do that now. This pub has a helper who runs the whole service on its own: the checking, the ordering, the timing, the ladling, and the fixing. That helper is software. The industry calls it an agent.

From answering to finishing

Everything you have met so far answered questions. The carrot sorter labelled. The Friday counter counted. The recipe writer invented. The chatbot explained. Every one of them waited politely for its next question. An agent is built the other way round. You give it a goal, not a question, and it works until the goal is met, whatever that takes. Its loop has 4 moves: plan the steps, use the tools, check its own progress, handle the surprises. The tools are ordinary: the phone, the ledger, the supplier list. So is the memory. It knows the regulars and their usual orders. It knows what the storeroom holds. Nobody tells it the next step. After every move, it asks itself what the goal still needs.

Agents already around you

Agents already work around you, mostly invisible. A bank system that once only answered questions can now block a stolen card and order the replacement before you finish your tea. A travel assistant that once only searched fares can now hold the seat and book the hotel. It reschedules the connecting flight, and it puts the itinerary in your calendar. It is the same shape as my pub: goal in, steps chosen, tools used, job done.

The apron is yours

Now the apron is yours. The order says: 12 bowls, to be collected, 7 tonight. Walk the whole service in your head, step by step. Do not skip the messy parts. Where do you start? And what do you do when the bread runs short? I give you three seconds.

Pause here for three seconds.
