It's all relative isn't it.
I was a kids performer for 25 years and latterly decided that I had had enough of being considered as nothing more than a highly paid baby-sitter. No not all gigs were like that, and I still have fond memories of many great parties and gigs, however it was the occasional nightmare party with no organisation, no parental control, noisy adult interruptions etc. etc. that spoil the job.
The problem is we cannot control the conditions, or can we? I wrote a thesis called "close-up to Cabaret" to highlight the differences between the two environments. The main difference being. Table magic conditions are, for the most part pretty standard. Yes you might have to deal with large table decorations blocking your view, little table space left to work on, etc. etc. But nothing usually two extreme.
It's the cabaret/parlour magic environment that poses the most challenges.
With magic we need to consider: Sight lines, audibility, lighting, space, maybe height clearance and stage width are essential, access to the stage for props and audience participants etc. etc. To cut the sales pitch short. If the conditions are not right..
Walk away did I hear you right you ask??? Yes I am suggesting that if you have given the booker, agent, client a contract stating the conditions you require to perform and they do not provide them. DO NOT PERFORM. If you do and you flop the audience will never know why. They will only remember "The Great ***dini" was duff. His act sucked. You may not even get paid, without a fight, but this will cost less than losing your reputation will.
Now kids party performers can't really expect party bookers to give you them all sorts of technical support but certain things can be controlled. Sufficient space, a responsible adult to be in the room at all times etc. Make it VERY clear that without these conditions you will not be able to perform. Respectable clients will respect your requests as they will understand it will help make their party go well. Those bookers who complain about your conditions should make the performer reconsider taking the gig. This for me is a red flag and from experience, proved correct more than once.
I was fortunate to be in a better placed financially in that turning down a gig would not result in no food on the table as I as I also had a full time job and I appreciate this may not be the case for all, but sometimes our sanity is more important the than the cash.
The best you can do its put this gig behind you, learn from the experience and be prepared to say "sorry I can't perform here" and leave with your dignity intact.
