Find fault with hotel vent stuck in awkward position? (5,5)
I believe the answer is:
split hairs
'find fault' is the definition.
(to split hairs is to find fault with something)
'hotel vent stuck in awkward position?' is the wordplay.
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'vent' becomes 'air' (synonyms).
'stuck in' is an insertion indicator.
'awkward position?' becomes 'splits' (as in doing the splits).
'h'+'air'='hair'
'hair' put into 'splits' is 'SPLIT HAIRS'.
'with' is the link.
(Other definitions for split hairs that I've seen before include "a trichologist may deal with" , "Make pedantic distinctions" , "Quibble" , "cavil exceedingly" , "Make petty distinctions" .)
