Get feedback you can use with a 5-question Google Form

Help me make a short customer feedback survey to build in Google Forms.

My business: [what you do]
When I'll send it: [e.g. the day after the job, after the third visit]
What I want to find out: [e.g. why people don't rebook, what they'd tell a friend]
A decision the answers will help me make: [e.g. whether to open on Saturdays]
How I'll send it: [e.g. text, email, QR code on the receipt]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. No more than 5 questions, each with its question type (multiple choice, scale 1 to 5, short answer) and the options written out.
2. One open question that gets real answers, not "any other comments?".
3. A message to send with the link, under 40 words, that says how long it takes.
4. A one-line privacy note: what I'll use the answers for, and that names are optional.
5. How to read the answers each month: what to count, and what would make me act.

Use only what I've given you, leave blanks for any price or fact I haven't given, and don't invent anything. UK English.
