I would like to know is the verb to arbitrate used only in very formal situations (related to law)?
If so, which word can we use for more casual situations like scenarios below.
Situation 1: In a semi-formal meeting with workers from the same company. In a case possible dispute between colleagues, does another colleague mediate or arbitrate?
Situation 2: A trivial dispute between neighbors because of dogs, or a quarrel between friends at a school
Situation 3: In a bar brawl. I think it would sound funny if somebody says "I tried to arbitrate the brawlers/fighters but they kept on."
