Last time I did an engagement party there about 10 kids running around.
They were on the stage, jumping off it and all over my gear.
I got fed up with it and asked over the mic for the kids parents to remove them from the stage as something was going to get broken.
No response at all.
So I turned off the disco and the client asked me what was going on.
I told him and he told me the kids were on their own, their parents had gone off clubbing leaving them with me to look after !
