Considering that I usher concerts fairly regularly… I have no problem escorting people out of the hall, revoking their tickets, or whatever it takes to maintain a quiet atmosphere.
On the opposite end of things… one of the rudest audiences I’ve ever played for was a very small audience. It was a series of solo performances in a recital, and they refused to applaud for anyone that they weren’t close friends with. It was the only time I have ever had ONE person applaud for me. I didn’t even bow. I ended up getting up and walking straight offstage without acknowledging them (they talked as well).
