How should I pay for dinner with my best friend or friend?

There will be unexpected situations. For example, some people organize a dinner party. When everyone was full, they found that the initiator was drunk and could not pay the bill. Who should pay the bill at this time? There is no doubt that the sponsor's friends should pay the bill. In such a dinner party, the friends of the organizer played a helping role. If the sponsor drinks too much, naturally, friends should take the initiative to pay the bill. Afterwards, the sponsors will return the money to their friends. Of course, friends can choose not to accept it.
