also make sure you think really carefully about your tricks. While this may seem anal, remember that you are giving at least a dozen shows, so each tables' show must be as slick as if you were doing a full stage show. I would personally never do just card tricks for example, what I do is have 'groups' of tricks, e.g. the beginning trick is always an eyecatcher. There are some really cool eyecathers about, raven, cig thru coin, vanishing deck, anything to get their attention thats magical. I try to spend what seems like 10 mins at each table, but you get a feel for when its time to move on. Because I don't like them, I'd always do 1 trick with a deck max, most people IMO know at least 1 card trick which is usually some kind of 'is this your card???' so i always do something a bit dofferent, ambitious card is fast and funny always goes down well for example, or a brainwave deck. Sponge balls are my fav for hopping, they can use everyone in the table and are funny and surprising, and the magic happens in their hands. They're also unusual little things to look at and feel. Find something that works for you. Then there's coin tricks, which I like. You can do anything here and as everyone knows coins and money magic is good, eye cathing. misled or something is good for the notes then you can say 'and ill keep this fiver for my tip...only joking' then hand it back and thay'll hopefully give it you anyway!!! What I like for close up is the funny things, quirky, like match box block, the mad stuff that no-one's going to predict. These always get the best reactions.
I would usually have 4 tricks for a table say, a quickie, card trick, sponge balls or sim then a finisher maybe a coin trick or something money based to encourage the tipping, and gives you chance to put in subtle lines for extra money grabbing. For each trick I would usually have 2 more similar, as whilst you are quite right, you will be performing to different people every time, you bet your life as soon as people realise theres a magician there everyone around will be watching, so have a few different ones. Also dont stuff everything in 1 pocket, plan it all so the props can be in your hands before they know it, make it slick, give ereything a home and practise re-setting everything as cleanly as possible before you move to the next table. You don't want to be going to the toilets to re-set your eight kings threatened to save...every time.
Anyway, thats my pennys worth.
