One reason people don't entertain is that they are worried about how their guests will behave. People are right to worry. Every once in a blue moon a guest will act out of line. It is extremely rare, but explosive when it happens. The Deans have seen people throw napkins, insult one another, get too drunk, and even get up and storm out the door. As searing as the moment is at the time, it can electrify the party and unite the guests against a common cause.
As always, it is not what happens but how it is handled that matters. As captain of the event, you must maintain your composure and lead your ship-ful of guests to calmer waters. When your attendees see you rising above the occasion, they realize that they can, too. They will form their own opinion about what happened. Sometimes bad behavior is a one off and can be excused. Other times the person is a reprobate and needs to be expunged from your life.
