Mei & the service-due reminders

A six-minute task became thirty seconds — but nearly leaked a customer's details and an invented price on the way.

What Mei pasted — Monday 8:47 AM

“Write a friendly service reminder, max 4 sentences, offer Saturday morning, ask them to confirm. Match the tone of this past email. Customer's message: Hi is this Summit? Aircon at Blk 214 Bishan St 23 #10-115 noisy again, last service Jan. Can come Sat? — Mrs Lim 9123 4567

What came back — 30 seconds later

“Hi Mrs Lim, thanks for reaching out! It's been a while since your January service, so your unit is due for a check. We can offer this Saturday between 10am and 1pm — servicing starts from S$80 per unit. Just reply to confirm and we'll lock it in!

Right — clear constraints. The time slot, length and confirmation request made the draft usable. A past email preserved Summit's voice.

Wrong — personal data. The customer's name, unit and phone number went into a personal AI account.

Wrong — invented price. Nobody supplied “from S$80 per unit”. It sounded confident and nearly shipped.

The save. Mei read the draft before sending — the right instinct and the only thing between the price and the customer.

Fix 01

Redact to {name}/{unit}/{phone} before pasting; use an appropriate business account with training disabled.

Fix 02

Add one limit: “Never include prices unless I give them.”

Fix 03

Save the working prompt so the saving does not evaporate next Monday.

The lesson Be specific, match your voice, and never trust a price the AI wasn't given.
