Then, it seems, that the best way to resolve the issue is to engage Acumen in celebrating a holiday you want to share with the rest of us. And I think you'll find most everyone to be very excited to participate and to help with the planning, as well.
Though the warden was Sentience at the time, one of the other prisoners succeeded in convincing Sentience to call us all "inmates", rather than "criminals". The system's more or less obliging.
I, for one, would be very interested in trying this Cortene, though I don't know enough about the holiday to take point in approaching the system to request it.
