"I was just about to pay," Old Meng said sternly.
The man immediately laughed, "So that means you haven't paid yet, right? I paid my money! Whoever pays for the goods gets to own them! Hand it over! Otherwise, I won't be polite to you!"
"How are you going to be impolite to me?" Old Meng barked angrily.
"I'm warning you, old fart, we're about to celebrate New Year, and it's better for everyone to be cordial. Hand over the sweet potatoes right now, and I might let you off the hook; otherwise, don't blame me for not respecting the elderly and loving the young!"
To talk about 'respecting the elderly and loving the young' after calling oneself 'old man'?
Old Meng was so angry his face turned green, and he became even more reluctant to back down. He reached into his pocket and took out his money, pulling out a one yuan note to give to the vendor.
"Take my money! Refund him that one yuan! It was clearly me who bought it first!"
