Is it any help to point out that an AFIS can NEVER issue instructions? They are what their name name says, an "information service".
IOW: your query sounds like being "without subject". At a non-controlled aerodrome, everything is done "at pilot's discretion". The radio person is there to assist you, and will pass every information that might me useful to you, in her/his judgement. I've never met or heard any that wasn't very able and very helpful and very correct, and it takes some degree of art to combine all those. But all decisions are up to your very own self, captain!
