joe and poke in prison for robbing the bank

joe, making small-talk so, have you ever been in prison before?

poke yeah

joe oh, really? what should I expect from this??

poke imagine prison is like a... imagine a grocery store, and imagine you're locked in that grocery store. but you can sell the food, basically, in the grocery store you can sell it because it's there and that's what it has to offer. you can sell the food so you can make money, and once you make enough money, you can leave the grocery store.
