Leopard Buying Octopuses

"Do you want a portion? Three skewers cost ten yuan." The stall owner immediately asked.

Parker understood that there was no free food in the world. The stall owner would definitely want something from him before giving him the food.

It so happened that the stall owner was done grilling the three skewers of octopuses, handing it to a young man at the side. That young man took out a wrinkled ten yuan note, placed it on the table, and left.

Hmmm? A piece of paper could be traded for food?

Parker opened his almond-shaped eyes, turned his body, and revealed a vulgar-elated expression, stared at the ground, and walked away.

The stall owner looked at the blond-haired young man strangely for a while, then took out ten more octopus skewers and started to cook them.

Parker looked around the ground for a while but wasn't able to find a similar type of paper. He only found balls of white tissue paper.

Forget it, he should just give it a try.
