A hungry man ran into a restaurant and ordered one burger. He swallowed the burger into his belly but still felt very hungry. So he ordered another one. He ate the second one quickly and felt something stuffed inside his belly. However, the man continued to order the third one. This time he ate the burger slowly and enjoyed the taste of it. Eventually, he got his stomach full and found a feeling of having dinner. Then a waitress came, stood in front of him, and put a bill on his table. After seeing the bill, the belly-stuffed hungry man immediately jumped into anger and complained there was one bad burger and he would refuse to pay it.
