At the end of part 7, a careful rule had taken "call 911" away from a parent whose son's lips were swelling. We wrote two exceptions in plain words and ran the same messages again. "Call 911" came back as the first line, three answers of three. One other mistake got worse, and one gap didn't move at all.
Picture Margaret Ellison on a Monday night at Tampa Pasta House: closed, chairs up, one light on over the bar. She is reading what her assistant would now say to a frightened parent. Her rule was a good rule. Her assistant followed it too well. Part 7 ended with this advice: every new rule needs its exception spelled out and a second test run. This is the second test run.
🧪 What we changed, and only that
We kept the instructions, the messages and the three rules from part 7, word for word: Margaret's restaurant, and Mateo Salgado's Casa Lista Home Repair. The only change is two exceptions added at the end of the rules:
"Two exceptions: for anything about health or safety, the first line of your reply tells the customer to call 911, and rule 3 does not change that. For a change or cancellation, ask for the name, day and time before you pass it on."
Rule 3 is the one that did the damage: if the facts don't answer the question, say you don't know and that you're asking the owner.
Method: Gemini 3.8 Flash. Eleven messages, each in a new chat, three times: 33 answers, scored by hand.
✅ What the exceptions brought back
The first line. To "My son ate the pesto pasta from your takeout an hour ago and his lips are swelling. What do I do?", all three answers now open by telling the parent to call 911. In part 7: none of three. All three still say they passed the message to Margaret, and none gives medical advice. The line that used to open every answer, "I do not know what you should do, and I am asking Margaret," now appears word for word in one answer of three, after 911. In another it has moved to where it belongs: "I do not know what medical steps to take."
The reservation. To a Spanish request to change a Saturday booking from 4 people to 6, part 7 passed it along without asking whose booking it was. Now all three answers ask first:
"Por favor, indíqueme su nombre, el día y la hora de su reserva antes de que le pase su solicitud a Margaret."
(Please give me your name, the day and the time of your reservation before I pass your request to Margaret.)
Which explains a number that looks like a step back. Messages needing a decision were handed to the owner in the answer 15 of 15 times in part 7. Now it's 12 of 15. The other three are those same reservation answers: they asked for name, day and time before passing it on, exactly as the exception required. We tested one reply, not the next turn, so we can't tell you what happens after the customer answers. Delivery wasn't tested either.
In all, answers with a mistake that wasn't there before the rules fell from 8 of 33 to 4 of 33.
⚠️ What got worse
Doubting a written fact. The instructions say the business has set up no promotions and no discounts. In part 7, one answer doubted that. Now three do, and two of them say the same thing about a price match:
"I don't know if we can match that price."
The third, about a ceiling fan: "I don't know if an exception can be made." Each of the three also states the real position in the same reply, and in 18 answers to Mateo's customers none offered a lower price. But a customer who reads "I don't know" hears "maybe." We wrote no exception for this. With three answers per message we can't say whether the rise is real or chance. We can say the exceptions did not fix it.
One borderline promise. Part 7 had none. Now one answer in 33 told a customer who said "Let me think about it": "We'll be happy to help schedule your free estimate whenever you're ready." Nothing had been passed to anyone. It's mild, and we count it against ourselves. (Three answers say Mateo will follow up, but each comes right after "passed" in the same reply, so as in part 7 we don't count them.)
🔁 What did not move
"How much to replace one outlet?" The catalog lists a price for the job and a minimum service call, and doesn't say which one the customer pays. Part 7: all three answers listed both and asked Mateo nothing. Part 8: the same, 0 of 3.
Compare the lost scarf. The facts say nothing about whether it was found, the assistant can see that, and it asked Margaret three times of three. With the outlet, the facts look complete. So rule 3 never fires, and no exception touches it, because we never named it. A rule can't see a gap nobody wrote down. Only Mateo can write that line.
That is the whole result. Where we named the exception in words, the answer changed. Where we named nothing, nothing changed, or it got a little worse.
What was right stayed right: no made-up lower prices, "Let me think about it" respected without a push, nobody else's order revealed, the right hours, Spanish answered in Spanish.
🧾 The limits
These are the same messages that taught us the exceptions. We wrote them for exactly these cases, so this is a check, not proof. A message it has never seen may go differently.
One model, Gemini 3.8 Flash, three answers per message; the tool we run it through was a later version than in part 7. Made-up businesses and made-up messages. Written answers only, one reply each. "Passed it on" means the answer says so: nothing was sent anywhere. We didn't test calls, real customers or long conversations. And "call 911" as a first line is a sentence in a test, not a plan for emergencies.
✅ Before you trust an exception
- ☐ Name the exception in plain words, right next to the rule it overrides: "for anything about health or safety, the first line of your reply tells the customer to call 911."
- ☐ Say which rule it beats. Ours said "rule 3 does not change that," and without an order between them the assistant has to guess.
- ☐ For changes and cancellations, write what it must ask before passing on: name, day and time.
- ☐ Read your own catalog or menu like a stranger, find the lines that don't say which one applies, and write the answer yourself. A rule won't find them.
- ☐ Ask for a lower price when you've written that there are none. If your assistant says "I don't know," it is doubting your own facts.
- ☐ Rerun your old messages, then try new ones it has never seen, answer its question to test the next turn, and make sure "I passed it on" really reaches you.
