Ok, so this has happened to me a couple of times, I perform a trick to say 3-5 people and one of them guesses the correct method and goes "I think you took 2 cards and showed them as one" etc. (not necessarily in a rude way) or part of what the spectator guessed was true. This inevitably disturbs me and the rest of the spectators and everyone just look at me hoping for an answer. I completely freeze and all I can say is "Nahhhh its a completely different method" and so the same spectator goes "Do it again" to which I cannot agree (duh). And so the environment almost feels like the spectator who guessed was right and I lied. So what's the tight thing to do? (This is different from messing up a trick, the spectator doesn't necessarily 'catch' anything)
