Cutie gets old sandwich for help

Two grandpas travel in search of new impressions. They arrive into a new town but accidently get lost. They try to use the map but fail. So what should they do in order to find their hotel and to spend a night in a cozy place? Of course, they come up to a cute girl and ask her for help. Luckily, she agrees to show them the way and even to see them to the door. Grandpas want to thank the cutie for help and they invite her into their room for a spicy sandwich.
