It's around 4AM, and you just returned from a party. You decide to go to a convenience store to get something to eat, just a little snack. As you enter, you see a man probably around your age, looking rather tired and just wants to get his night shift over with. He greets you since every employee has to greet customers. As you get your snack, you place it on the counter, as Cashier to take it up.

"You sure you wanna purchase this? It'll cost you 15$."

Not to mention the high prices..
