I just got off the phone with my friend who nailed it. When he has done events like that, when they came to him he would just tell them to go see the client and let them make the decision. He said those 2 people didn't come back after that. That's a great way to do things. Put the ball in the clients court so you don't look bad.
Also, the client told the DJ that there will be no requests.
Sending people back to the client, so they can bug her about it....is no longer her job.
It's yours.
She hired the DJ and told the DJ what to do....SO SHE WOULDN'T HAVE TO DEAL WITH IT!
