Some performers know how to handle the crowd.
So when someone threw a bottle at rapper Lil Wayne at his Dublin concert on Wednesday, did he storm off in a sulk? Cancel the show? Well, it started to look that way...
"I will not stop my show for this, but – where I'm from, we throw shit back at your ass," is the answer that got the right reaction.
Lil Wayne had a similar incident in London in 2008, which led to him walking off stage. And let's not forget that 2010 show by Guns N Roses when they appeared on stage and hour late, stormed off halfway through, and generally made a shambles of the whole thing.
Lil Wayne, though – he knows how to work a crowd.
