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

Which condition was difficult to interpret?
What explanation did the error provide?
What example would help?

Author notes / illustrative keys where applicable:
1. A difficult promotion condition identifies qualification wording that shoppers cannot apply confidently. Clarify verified exclusions without collecting private codes or assuming eligibility.
2. The error explanation reveals whether a promotion's stated conditions connect to the rejection encountered. Clarify verified qualification wording and support routes, without requesting private codes or inferring a customer's entitlement to the offer.
3. A useful example identifies how to explain the stated promotion rule in practice. Use labelled synthetic cases that follow current official conditions.
