Agree!
I view corporate work differently from other forms of magic. The company that is thinking of hiring you are usually extremely conscious of their image and will be ensuring as far as they can that anyone associated with their trade stand will enhance their products and corporate reputation. Most organisations spend serious money on their corporate image so you should be aware of this. Always find out as much as you can about your client in advnace and NEVEr be afraid to ask them for information that you can use to their advantage.
In this arena there is little or no margin for error and you MUST be a 'natural' with people and accept that the punter is always right, even if they aren't. No-one's going to thank you, least book you again for pointing out that the MD of their biggest customer is a moron because he can't shuffle a deck (and boy, have I met a few moron's in my time).

Having Tipsy the Magician performing on their trade stand will pehaps give the impression that you've had one too many, even before anyone see's you


Just out of interest, I went to a trade show a few weeks ago at the NEC in Birmingham (IFSEC) and saw a magician on a trade stand (Securit Ltd). Was wondering if he was a TM member?
