i can't put it better then the 2 guys who already posted.
as paddy said he's a proffesional, and Robert_V_Frazier is learning about the subject (as far as i know...).
i already have an amount of card tricks that could entartain for about 3-4 hours, it would be enough for as many routines with cards as i want for restaurant work, but i do need to vary my act with more things.
the basic routine for restaurant work is a card trick, a coin trick, and something else (doesn't have to be in that order).
i'm right now, like many other people posting in this forum, is working on getting a big amount of coin tricks into my arsenal, so i could vary as much as possibble.
i also think that being a proffesional restaurant performer means being a proffesional magician first! the restaurant is not a place to practice ur tricks on real people instead of the mirror. u first have to be an excellent magician, if u won't, then if another magician would come applying for the job and the manager would simply see that he is a lot more experienced, he wouldn't think twice and hire him over u.
i can say about myself that i'm right now performing for kids, adults, mentalism, stage, closeup, whatever... but i havn't got into the restaurant buisness yet, and i belive that i'm still NOT experienced enough to start with it. i think i'll be ready after i'll gain more tricks and routines possibble with coins, and how to talk with people better face to face.
if u were wondering how old i am, then i'm only 17, and i think i got enough time to gain more experience befor i want to start doing the restaurant work.
i know about paddy and Robert_V_Frazier that their a lot older, and i admire paddy for starting his career as a magician just a few years ago, i think we can all learn a lot from him as a magician.
the best advice i can give u is to start performing for everyone u can (if u havn't done it yet, coz restaurant work is NOT something to start with), by performing diffrent kind of shows u would gain the ability to talk to people and be able to make jokes and get laughs the whole time during ur act, which i think is what were all after, entertaining. as for the restaurant, that's NOT the perpose, the perpose is to EARN MONEY to the restaurant in any possibble way.
if u don't think ur'e ready to do performences yet, then keep practicing, don't give up. i've started doing magic seriously only 2 years ago (bought my first bicycle deck then...), after that i only bought the 3 AOA books from penguin (which is a must have if u ask me), and i've only "spent" 350$ on magic so far. i don't mean to brag (spelling?) here, i just wanted to state that anyone can do magic on stage, for kids, or whatever. but in restaurant magic the magic is much more personal, coz u have to pay attantion to the people and what they say. like if someone says: "i saw u put a card in ur hand, turn the hand palm up!" in that case, u gotta have the ability to know what to say.
anyway, this post is long enough, i can go on and on about restaurant magic, but all i can say is that ur'e not ready yet, and will not be ready for the close time, keep practicing, and best of luck!
