If this story is not about the DJ...it's because he was not included in the story.
it only matters that we haven't heard his side...and neither have you.
You are truly playing the fool.
The loser DJ whose "side of the story" you think is so important is NEVER going to hire you for anything. I can only guess you are looking for excuses you can use in your own future follies. The story is about what it takes to avoid getting stuck with these losers.
I'm care only about the customer's experience because that is what informs my business, and this is why I will NEVER find myself in such a position. I don't care how many excuses the loser DJ has for being a failure. I care what matters to customers and what expectations they have regarding the service. It was a very good story, and no I don't need to hear sh** about that DJ.
Proceed at your own foolish risk.
