You walk into the small corner store, it was around 4AM and you were looking for a snack or something to eat. You have ten dollars, which is just enough for both. As you walk around, the cashier was watching you, his ears twitching a bit. You couldn't really decide on what you wanted and eventually decided on an iced coffee and some potato chips. You walk up to the counter to buy them, and the cashier gets up out of his chair, his tail wagging slowly. He scans the items. "That's eight dollars."
