Any Other Crabby Listeners Out There?

Few things annoy me as predictably as public speakers and musicians who rely on their charm and/or notoriety to "wing it". Unless asked to speak or play extemporaneously, what excuse does someone have to not prepare or rehearse?

Not long ago, I watched yet another arrogant, under-prepared individual try to bluster his way through a fifteen minute speech. He didn't appear to be working from notes. But even if he was, his remarks had no discernible theme - certainly not one related to the event - the speech had no flow, the whole debacle demonstrated no respect for his audience. Sitting there, I was reminded of a Kinks concert from many years ago. Each time those clowns flubbed a song - or depended on the audience to fill in a lyric they didn't take the time to memorize - I got more incensed. I paid money for this? Despite loving their music at the time, I never bought another Kinks record.

I'm not expecting perfection. Seams show, mistakes are human, and I actually don't enjoy speeches or
performances so buttoned up they strike me as sterile. And it's also possible my crankiness about off-the-cuff performances is connected to my own propensity for being hyper-prepared. But it seems to me there is a subtext to the sloppiness these improvisers foist on us, the listeners - "You are not important enough that I would spend time preparing or rehearsing."
