Time of payments: edited round number gets stuck up (6-5)
I believe the answer is:
toffee-nosed
'stuck up' is the definition.
(both can mean snobby or superior)
'time of payments edited round number' is the wordplay.
'time' becomes 't' (abbreviation).
'payments' becomes 'fees' (I have seen 'Professional payments' mean 'fees' so perhaps 'payments' could also mean 'fees').
'edited' becomes 'ed' (publishing abbreviation).
'round' is an insertion indicator.
'number' becomes 'no' (abbreviation for 'number').
'fees'+'ed'='feesed'
'feesed' going around 'no' is 'feenosed'.
't'+'of'+'feenosed'='TOFFEE-NOSED'
'gets' acts as a link.
(Other definitions for toffee-nosed that I've seen before include "Supercilious (with a sticky hooter?)" , "Stuck-up" , "superior?" , "Snobbish, patronising" .)
