With refreshments to eat, your one-time previous experience bad enough? (5,3)
I believe the answer is:
twice shy
'previous experience bad enough?' is the definition.
(ref to the phrase 'once bitten, twice shy')
'with refreshments to eat your one-time' is the wordplay.
'with' becomes 'w' (abbreviation).
'refreshments' becomes 'ices' (an ice or ice cream is a type of refreshment).
'to eat' means one lot of letters goes inside another (word on the right has word on the left to eat).
'your one-time' becomes 'thy' ('thy' historically meant 'your').
'w'+'ices'='wices'
'wices' inserted within 'thy' is 'TWICE SHY'.
(Other definitions for twice shy that I've seen before include "'Once bitten, . . . . . . . .'" , "See 9" .)
