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

Which printing instruction was unclear?
What drop-off information was missing?
What alternative would help?

Author notes / illustrative keys where applicable:
1. An unclear printing instruction identifies a practical step preventing customers using the return label. Explain supported formats or official help without collecting tracking details.
2. Missing drop-off context identifies a practical handoff gap after obtaining a return label. Provide verified collection-point references and conditions, without treating label generation as proof that a return has been accepted.
3. A helpful alternative identifies what customers need when the usual label route is unsuitable. Confirm which return options actually exist before describing them as available.
