Ammo isn’t that expensive lol, if someone is going to rip off a vending machine/atm, the ATM would be, by far the better choice. 9mm is less than 15 cents per round right now. Unless the vending machine was filled with super expensive exotic ammo, you’d get maybe a few thousand dollars. For the risk of heisting a vending machine, that’s a pretty shitty payout for the would-be criminal.
