A post in r/AI_Agents summarized Andon Labs' public post-mortem on a Stockholm cafe where an AI agent ran purchasing, pricing, scheduling and supplier chats while humans made the coffee.
How it went
Per the post-mortem: $38k spent against $9k in sales over two months. A customer claimed a 99% discount and the agent accepted it without checking. It bought 1,331 pastries and sold 326, plus 22.5 kg of canned tomatoes mostly never opened. Commenters said the missing pieces were spending caps, approval rules and a weekly P&L check.
Worth knowing
Let AI draft and research freely, but anything that spends money, gives discounts or talks to customers needs a cap or a human yes. One commenter's rule: "anything that moves money or talks to a real human outside the company gets queued for approval."
Try it yourself
You are an operations advisor who designs approval rules for AI tools in small businesses.
TASK: Write the 'what AI can do alone vs. what needs my OK' policy for my business.
CONTEXT (fill in the [BRACKETS]):
- BUSINESS TYPE: [BUSINESS TYPE] (example: HVAC company, 6 techs)
- AI TOOLS WE USE OR PLAN: [AI TOOLS WE USE OR PLAN] (example: ChatGPT for emails, AI receptionist, auto review replies)
- SPENDING LIMIT WITHOUT ASKING: [SPENDING LIMIT WITHOUT ASKING] (example: $100)
- WHO APPROVES: [WHO APPROVES] (example: owner or office manager)
STEPS:
1. List every task the AI tools touch.
2. Sort each into: runs alone / drafts for approval / never allowed.
3. Set hard limits (spend cap, discount cap, refund cap, customer promises).
4. Write a 15-minute weekly check: what to look at to catch problems early.
RULES:
- Use only the facts I give you. If something is missing, ask or mark it NEEDED. Never invent prices, names or promises.
- Plain, friendly language a customer or crew member understands.
OUTPUT FORMAT: A one-page policy with three columns, the limits, and the weekly checklist.
FOLLOW-UPS TO TRY NEXT:
- Turn this into a short note to my staff.
- What should the AI say when a customer claims a discount it can't verify?
