This guide is ideal for money making.
First, attend roll call. This is highly important to making money, as i will describe later.
Roll call may happen 0-3 times a day, depending on the prison.
Find and accept all the delivery favors you can. Since everyone will be right next to each other, you can deliver items really quickly.
Deliver the items!!! You will make a decent amount of money, if there are a lot of delivery favors. If not, just wait until next roll call, than try again!!
