I'd recommend any multiple effect DVD by Jay Sankey. He is a restaurant worker himself, so all the effects are audience-tested. Added bonus is that his magic is often off the beaten path, making your magic likely unique compared to other magicians in your area (unless you live near Sankey himself).
Of course, he's got a somewhat crazy performance identity, so it has to fit you already, or you need to be able to adapt the routines to fit your own needs.
I agree, with most of it.
I highly reccomend anything by Sankey you can get your hands on. However, he is not a restaraunt worker anymore, and a lot of the stuff he releases he hasn't tried on anyone.
That isn't to say it is bad, it might even be that it is good in that all of it doesn't have to be done in Sankey style.
I really like everything he has ever put out. Buy as much as you can!
