As a promoter of a concert who refunded £48 to 4 people at half time in a concert, just to get rid of one of them, who came to me during the interval and complained that an adjacent table had asked her to shut up during the performance, and argued that, "No you hadn't", when I told her that she was clearly audible across 50 feet of the room where I was standing, and that I had heard her...I know where you're coming from!
Pure bloody ignorance, inconsideration...and why TF come to the concert in the first place if they don't want to listen?
