I think the idea here is to force them to develop some sort of empathy for what people who work in fast food have to deal with on a day to day basis and learn from it (which should reduce recidivism) as well as some punishment, hence the 30 day jail sentence and 60 days working in the job (or just 90 days in jail).
I'm personally in favour of this. A jail sentence is purely punishment, whereas this feels like a combination of punishment and rehabilitation which is rare but tends to provide better outcomes (this tends to be contentious so I won't provide links, but please do look it up if you get the chance).
I'm a dev manager... I have 3x4k monitors. I watch server loads, I watch the build pipeline and watch the commit logs etc.
Overkill these days, but I'm also a gamer sooooo....
