Which begs the question, what's the logical reason to having all of those vending machines scattered all over the city? I doubt it's to quench everyone's thirst. If it's for the purpose of having an easy access to weaponized animal helpers, then why not just have something that doesn't resemble anything with a purpose far from whatever that object was designed for? Why not just make portable weapon lockers which when opened releases animal helpers that when folded, looks far from something used for a drink. If it's to disguise those weapon dispensers, then if some normal dude drops a coin in it and expects a cold can of Pepsi, then what would happen?
We're not thinking about it too much, in fact, it doesn't even take much brain activity to realized how "silly" the concept is. I'm not saying it's bad, all I'm saying is that it's "silly".
