Suggestion to leave dodgy bar? Heads off without much analysis (9)
I believe the answer is:
intuitive
If this is the answer I cannot explain how the clue works.

(Other definitions for intuitive that I've seen before include "Innate" , "easy to understand" , "Sensed by something other than reason" , "with instinctive knowledge" , "Using hunch" .)
