You say you should have 6 routines. But when you are at the restaurant how many hours are you there? And do go then to go 6 different tables and show the 6 routines and then you are done? Or do you show any of the routines more than once?
Also do you have any suggestions for where to find commercial magic that can be done in restaurant? (maybe specific tricks you can suggest?)
Thank you for your time
6 routines is what was stated. In restaurant, strolling, or table-hopping magic, you don't need many effects. You repeat your routines to each table as necessary. Chances are that each of the tables you perform for are not close enough to get a glimpse of what you performed for another table. You also will not perform all 6 routines for every table (if any).
As for commercial magic for restaurants, I'm not sure what you mean by that. Try some of these items:
A deck of cards
Sponge balls or rabbits
US Half-dollar or english penny size coins
There is so much that you could use. Anything can be magic, but it's up to the person handling the items. Even a self-working gimmick can suck if the performer doesn't make it entertaining.
Back on topic. I agree with Paddy. Restaurant is not a place for beginning magicians trying to work their way up to the status of a restaurant magician that gets paid. Also, if he's not good enough to be getting paid, then he's probably not good enough to be doing it for free either. This is another example where a restaurant may get a less than professional performance that ruins it for the rest of the magicians trying to make a living. Like Paddy said, do not offer to perform only for tips or for free unless you are offering a free night as an audition. For practice, you might try performing at family gatherings or something like that.
