Mobile Wedding DJ's are usually the people who release tables to go through the buffet line at wedding receptions. Years ago I discovered that a great way to make this task more enjoyable for me was to perform close-up magic as I released those tables. What's funny is that a lot of my clients now request this as part of the reason they hire me.
This table magic thing is a great way to give the bride and groom something different and it always breaks the ice for a lot of people during the dinners. In addition it's just one more reason for the guests to remember how much fun they had at the reception. Ultimately (as any magician would tell you) I do this because I LOVE to watch the reactions people have to magic. That look of astonishment on a guests face is priceless for me. I guess I'm greedy in that way.
