a gumball machine with a quarter already inside, i was waiting for my dad to leave the checkout so i went to it just to mess around like usual, until a gumball came out of the machine, i had no idea the quarter was inside the machine, so i basically got a free gumball, i was younger at that time and my father was there when it happened, so he put another quarter in the machine for next person who uses it. also srry for making it long.
