I appreciate the advice. My material has been solid for 40 years for both restaurant and corporate events.

I'll correct this part of my post;
(The worst is when people that have a good view of me turn their chairs around!!! LOL )

Even with that correction the idea still remains. If they won’t turn to watch you engagement is an issue.

Did one show at a country club during a dinner and I will most definitely advocate against it if a client suggests it. One table had a great time because they were served first, done eating quickly and were able to enjoy majority of the show.

I did a corporate holiday event where the client initially suggested it. I told him it was a very bad idea and thankfully he agreed! Unless they are super adamant about it I hope to never do that again.
