Three types of buffet show indecision (4,3,3,4)
I believe the answer is:
blow hot and cold
'three types' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'buffet show indecision' is the wordplay.
I cannot quite see how this works, but
'buffet' could be 'blow' (both can mean to hit) and 'blow' is found in the answer.
This explanation may well be incorrect...
'of' acts as a link.
Can you help me to learn more?
(Other definitions for blow hot and cold that I've seen before include "Unpredictably, swing" , "Air-conditioning" , "as will the sirocco and mistral?" , "not steady" , "behave inconsistently" .)
