I walked out during Jim Davidson stand up show in Windsor, he spent the first 10 mins swearing and insulting the audience (who had paid good money to come and see him) disgusting!
I left the cinema during one of the Oceans 11 films, jumping back and forth in time, got so confused! Also The interpreter, was too confusing for my little brain. I went to the red carpet premiere of Inception met all the big stars, Tom Hardy, leo diCaprio, Cillian Murphy, (my name is...) Michael Caine, but should have taken a notepad as I could not follow it at all and was dreading all the celeb sycophants asking me what I thought as they were raving non stop about it afterwards. I also went to see Whitesnake play Hammersmith pally, David Coverdale had a cold, so it was a karaoke concert where the band played the music and expected the crowd to sing it themselves. There was nearly a riot in the lobby as hoards of people were leaving and VERY angry. They should have cancelled the gig, you come to hear him sing it, not expect to sing it yourself!
