It's been my experience with probation officers that they'll literally bend over backwards to attempt to avoid a non-custodial sentence for the person they're writing the report on.
(I think the USA and the UK might be different in this respect though, In the US, probation officers tend to train in social work departments. They're hotbeds of leftism and SJWs in their most extreme form. The USA seems to turn out probation officers who are more aligned with the punitive aspects of the criminal justice system -- but I'm really just going by what I've seen in the movies, where the probation officer wants to violate somebody's ass and send them back to jail. Nobody EVER gets violated in the UK. You'll get busted three or four times during a two year period of probation and every time your probation officer will be writing a report on why this person should be given a 93rd chance.)
But I could just imagine Nick showing up at the probation office for his pre-sentence report. PO is the standard archetypal UK liberal probation officer who never wants to send anybody to jail -- but after half an hour listening to Rekieta patronize him, tell him how stupid and inferior he is and how the rules that apply to the common proletariat shouldn't apply to him -- after half an hour of contact with Nick, he's immediately converted to the value of a custodial sentence and sees this first time middle class white offender as being the prime example of a man who would benefit from what we used to refer to as the 'short, sharp, shock.'
