I had an interesting gig last weekend.  Without boring you with too many details,  there was a little bit of trouble with some of the people in the place I was playing.   No fight broke out,  but there was a lot of shouting and tension in the air.   The owner ended up throwing out this group of troublemakers.

As a performer,  it raised an interesting question for me.   What do I do?   I felt kind of dumb continuing to sing and play while all of this is happening five feet away from me.    At the same time,  I felt like if the music suddenly stopped,  it would have drawn more attention to the matter and possibly would have disturbed more of the patrons than had already been disturbed.
