Being a bit cranky, perhaps, put together extremely insufficient, stingy tip (9)
I believe the answer is:
impatient
'being a bit cranky perhaps' is the definition.
I can't judge whether this definition defines the answer.
'together extremely insufficient stingy tip' is the wordplay.
'together' becomes 'in tandem' (working in tandem is working together).
'extremely' says to hollow out the word (remove centre letters) (only the extremes of the word are used).
'insufficient stingy tip' becomes 'patient' (I can't justify this - if you can you should believe this answer much more).
'intandem' with its centre removed is 'im'.
'im'+'patient'='IMPATIENT'
'put' acts as a link.
Can you help me to learn more?
(Other definitions for impatient that I've seen before include "dying" , "appeared anxious" , "those who hate waiting" , "Restless or short of temper" , "restive" .)
