Not sure what to do, hints tea should be served (8)
I believe the answer is:
hesitant
'not sure what to do' is the definition.
I can't tell whether this definition defines the answer.
'hints tea should be served' is the wordplay.
'should be served' indicates anagramming the letters.
'hints'+'tea'='hintstea'
'hintstea' is an anagram of 'HESITANT'.
Can you help me to learn more?
(Other definitions for hesitant that I've seen before include "Slow to act/speak" , "The Saint? (anag)" , "Doubtful" , "Reluctant (to speak, act)" , "Reluctant, vacillating" .)
