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

What service were you waiting for?
What did the queue display tell you?
Which waiting update was missing?

Author notes / illustrative keys where applicable:
1. Read for service context. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
2. Read for display comprehension. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
3. Read for update need. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
