How I dealt with a heckling clarinet player

Lately, I've been having fun dealing with people who behave badly at my shows. Not really hecklers, more like loud talkers or sloppy exiters. But the other week, I had a new situation. The backstory: I did a set at a variety show. Before me there was a band. After the band got off, they hung out in the back of the room by the bar. While I performed my set, one of 'em kept noodling away on his saxophone. I yelled at him to stop playing saxophone. He got indignant about the fact that it was a clarinet, not a saxophone. I thought he was a cockmouth. So I told him so. Here's a link to the audio.
