Earlier, I noticed a small little detail about Vault 22; it has a Nuka-Cola machine. Now, you're probably thinking, "yeah, people get fat and thirsty", but think about it; would the contractors of Vault-Tec really just buy a vending machine and stock it with Nuka-Cola itself? Don't companies like that usually have
partnerships to help compensate for that service?
So, what I'm really getting at, could it be possible that Vault-Tec could have done more business with a big corporation like Nuka-Cola than sell caffeine to the Vault's residents?
