i've only walked out of one show before it was over. Raekwon showed up in San Fran around the time Immobilarity dropped and after about 20 minutes I just bounced... Poor sound, too many people with microphones, plus Rae just wasn't captivating as an MC, live at least... I also remember seeing Deltron 3030 around the same time and not being impressed. I'm not a big Del fan so that had something to not be caught up in the show.

But by and large, I've had positive experiences at live shows. I can't complain much, I suppose.
