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

Where did you look for assistance?
What question was difficult to route?
What staff identification would help?

Author notes / illustrative keys where applicable:
1. Use this answer to locate the part of the experience that needs explanation. The example issue to investigate is: visitors cannot distinguish volunteers from venue staff.
2. Difficult routing reveals whether an attendee could identify the role responsible for a practical question. Explain the approved help points and scope, without collecting staff identities or treating friendliness as service readiness.
3. Turn the requested improvement into a testable next step. One illustrative action is: use clear role labels and escalation contacts.
