If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

What did you expect from the appointment?
Which preparation detail was unclear?
What location information was missing?

Author notes / illustrative keys where applicable:
1. The expectation reveals what service the shopper thinks the appointment includes.
2. The unclear preparation identifies an administrative detail to explain.
3. The missing location shows what public meeting-point direction is needed.
