Customer interview script (Mom Test)

Builds a customer interview guide in the spirit of The Mom Test: questions about past behaviour, not opinions, plus the signals of real commitment.

Write a customer interview guide to test this idea, following the principles of "The Mom Test" by Rob Fitzpatrick: ask about their life and past behaviour, not about my idea or their opinion of it.

Idea or hypothesis: {{HYPOTHESIS: e.g. "small online shops lose sales because they answer WhatsApp too slowly"}}
Who I will interview: {{INTERVIEWEE}}
What I need to learn to decide: {{DECISION: e.g. whether to build, who to target, what to charge}}

Rules:
- No hypothetical or leading questions ("would you use...", "how much would you pay for...", "don't you hate..."). Ask about the last time something happened, what they did, what it cost them, what they tried.
- Do not mention my idea until the end, and only if it helps.
- 10-12 questions maximum, in a natural order for a 20-minute talk.

Output exactly:
1. Opening (2 sentences I can say to set up the call without pitching).
2. The questions, grouped: their context, the problem in practice, current solutions and spending, priorities. For each question, one line on what it reveals.
3. Follow-ups to dig deeper ("tell me more about the last time...", "what happened next?").
4. Bad questions I might be tempted to ask, and the better version of each.
5. Signals of real interest versus polite interest, and the commitment to ask for at the end (time, a meeting with the decision maker, a pre-order).
6. A note-taking template: facts, quotes, emotions, commitments, next step.
