Reborn as a Vending Machine, I Now Wander the Dungeon

After dying in a traffic accident, I find myself standing beside an unfamiliar lake. My body won't move, and I can't hear my own voice—but when I try to cry out in confusion, the words that escape me are not what I expected: "You're a winner! Get one free!" I-it seems I've been reborn as a vending machine...! Now I can do only what an actual vending machine is capable of. Moving on my own is impossible, and holding any kind of meaningful conversation is out of the question. Just how am I supposed to survive in a fantasy world's dungeon like this?!
