An article I saw on the net... thought I'd share with the rest of forumers.

Some Thoughts on Spectators


I think that we are dealing with two different types of spectators.
They are:

1) I think I know how he might have done it.

This is the non-challenging spectator that just thinks they might have figured it out. Many times their ideas are pretty far out there. (The cards are magnetic, the cards change when they heat up with your hands, the cards are chemically treated, they went up your sleeve.) Proving the fairness (of the trick you are performing) here will add to the magic of the moment. The magician must have something of interest to say during this process, otherwise it becomes a little boring and breaks the tempo. For instance, if the spectator says, "I think all the cards are the same." I will show the cards to be different and say something like, "No, they're all different, otherwise the Friday night poker game would be very boring."
These type of spectators I will adjust the presentation for and have a good time. There have been those times that I have done only one trick for a group and then spent the next 10 minutes in a fun and spirited conversation. This has the effect of showing spectators/patrons/customers that I am not going to push magic down your throat, I'm just sharing a good time with you along with a magic moment.

2) You can't fool me and I will catch you magic boy.

These are the spectators just don't seem to enjoy magic. They take everything as a personal challenge to their ego. They will blurt out a secret even if it can not possibly be the answer. Comments such as, ( I did magic when I was a child also; Aww, it's just a trick deck; or nod their heads in a knowing way with a smirk) These are the challenging spectators. They will only enjoy your performance if they can belittle it. The degree of antagonism might be different but the thinking is all the same. For these people, I will not waste my time proving anything. If they are at a table with other spectators that seem to be enjoying the performance, I might do a quick proof , but nothing more.
There will be nothing gained by proving anything with this spectator; because, even if you prove everything is fair, others will see this as a contest between two people. The atmosphere will become less enjoyable and more tense. The 'who is going to win and get their feelings hurt' attitude starts to creep into the performance.

Many times we can have a night where we amazed 30 tables of spectators, but there was that one table and they didn't like the magic/us. We start to obsess on this one table. We forget that thirty other people really enjoyed it. But, no, we must have everyone enjoy us and think us amazing. This is when we get into those no-win proving situations. Even at an academy award winning movie there are those who don't like it. It is
the same with our performances. I believe that the magicians that have good people and performance
skills know how to avoid and deal with the situations that we have talked about. There is no steadfast rule on how to handle these circumstances.
