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

Which instruction choice was unclear?
What preference could you not express?
What confirmation would help?

Author notes / illustrative keys where applicable:
1. An unclear instruction choice identifies ambiguity about what the delivery option actually permits. Review the label against supported arrangements without requesting addresses.
2. An unexpressible preference reveals a gap between supported delivery choices and the instructions presented at checkout. Explain actual options and limits, without collecting addresses or promising that every requested arrangement can be fulfilled.
3. A useful confirmation identifies how shoppers should know whether their instructions were recorded or passed onward. Explain the actual process without promising every preference will be fulfilled.
