When I used to do magic a few years ago. I really get nervous when the spectators are involved. But what I found effective in my case is to give them the proper instructions at the same time giving ludicrous reasons as to why.
ie. I want you to take a card and place on hand over the card to make sure that the magical effect of my invisible pixie dust doesn't go to waste.
they usually give me a WTF-look and comply. its worked so far back then. But since I don't do magic anymore I dunn ohow effective it can still be in making sure the spectator doesn't flip over the card (that is not theirs anymore).

You have to be careful with that. Sometimes it will clue in your spectator that you're about to pull a fast one on them and it can make them extra cautious.
A good (and hysterically fun) method I use to pull that off is with a massive, gut-busting distraction. I do a trick as part of my regular routine at the hospital where I have to perform an Erdnase exchange. Now, I could simply do the exchange without saying a word and be done with it, but unfortunately, those Chinese-made Streamlines I bought make sliding just one card smoothly off the deck with your palm heel nearly impossible without some effort. (The deck isn't all bad - it has two jokers that, while not identical, are close enough that my audience hasn't clued into it yet after all this time.) So instead, I tell the patient that I have to rub the card in a certain way, in order to get the magic off my fingers and on to the card. If there are other spectators, I'll say "In order for this to work, you have to stay absolutely quiet - they can laugh all they want, but you have to be quiet, OK?" At that point, I go into a wild, flailing mess of a dance while concealing the exchange, and the audience is laughing so hard they barely remember it's a card trick! Then I bring it in, settle down and get to the real business of the trick, with them absolutely none the wiser - they just think I'm trying to get a laugh out of my patient to take his or her mind off of where they are. (Which it does as a pleasant side effect!) Hmm...maybe I could also rub the deck all over my body like a bar of soap... :))
