Haphazardly managed activity in site supplying bread? (2,6)
I believe the answer is:
at random
'haphazardly' is the definition.
(I know that haphazardly can be written as at random)
'managed activity in site supplying bread?' is the wordplay.
'managed' becomes 'ran' (both can mean organised or was in charge of).
'activity' becomes 'do' (both can mean an event).
'in' means one lot of letters goes inside another.
'site supplying bread?' becomes 'ATM' (cash machine - bread can mean money#).
'ran'+'do'='rando'
'rando' put inside 'atm' is 'AT RANDOM'.
(Other definitions for at random that I've seen before include "willy-nilly" , "Haphazard" , "Casually" , "Without method or conscious decision" , "unplanned" .)
