if you are performing for any one in any environment. say, an office or even in school. there might be some individuals who might be skeptical and simply not interested in magic. and you wish to perform in such an environment for the rest to enjoy.

if these individuals were to say something like 'okay, i know you were showing 2 cards as 1' or 'it is hidden under your sleeves' after your magic is done, how would you react ? how do you 'prevent' something like this from happening or in the very least, minimize the negative impact of your whole performance among the group?
