I just discovered first-hand that some people who play duplicate bridge are not nice people. A new Director (not me) was directing the games tonight and made a significant error. His partner and another person threatened to leave and made a scene. We tried to recover but as of tonight, I haven’t been able to do so. Perhaps an hour or so on the phone with ACBL will solve the problem. I was very uncomfortable with the behaviour of one of the players. When I asked him to take his loud problems away from my table, he refused. I will give him one more chance.
