Who most likely is the speaker addressing?

Welcome, everybody, to this staff meeting.(92)I have to add a new item to the agenda since I received several complaints yesterday about the state of the lunchroom. I’m not going to name anybody at this meeting, but I have to say that I, too, am also disappointed by the behavior of certain staff members.(94)The lunchroom is a shared facility and one which provides all of us with a valuable service. Let’s keep it clean!(93)If you make a mess, clean it up. If you read the newspaper, return it to the table folded neatly when you have finished with it. If you use the sink, make sure you leave it clean. This is a question of basic good manners, and I hope I never have to speak to anybody here again about it!(94)
