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

Which join instruction was unclear?
What arrival detail was missing?
What fallback contact did you find?

Author notes / illustrative keys where applicable:
1. Read for join clarity. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
2. Read for arrival context. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
3. Read for fallback route. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
