Found a guest quarreling with a guest in the hotel area. What should the waiter do?

First, at least people above the supervisor level persuade the guests to a secluded place (to avoid affecting other guests); Second, don't get involved in disputes between guests, and don't listen to your own reasons (one of them says reasons, and the other will definitely say, you fucking fart! ); Third, pour two glasses of water (use paper cups to prevent the guests from dropping the cups in a rage). I don't have the strength to make any noise when I'm full.
