My not so good English will probably destroy the point I'm trying to make, but here it goes...
People are not stupid. They know it's some kind of a trick. They don't know "how?", but they know that it was some kind of a trick. So I wouldn't be so offended if someone called it a trick, instead of a miracle or magic. Somewhat intelligent people will think like this "Nobody was born with knowledge (special powers), so he must have learned that somewhere, so yeah, that is pretty great trick (TRICK)..." If there were really people that can do what we do (supernatural/magic), without using some kind of trick, those people would be all over the news and newspapers like the 8th world wonder. Or somewhere in CIA lab...
And for those people that truly believes in magic, supernatural and all that stuff, well, a simple double lift + revelation will be enough.
I mean, did anybody here believed that Copperfield has special powers? Or maybe David Blaine?
When I saw those guys perform, I was astonished and "my mind was blown blown" (TA reference

), but I never taught that they have special powers, or that it was real magic, I know that they had a way to do that somehow, but I didn't know how.
And if someone was really magical, would he be at that coffee shop showing "magic" to random people, or would he do something more useful for himself and others?
So, all we can do is try to throw the best show that we can, blow blow their minds away, and hope that they will remember us for a long time...
Don't read to much into it when someone calls you a magician and not Gandalf.
Magicians will always perform tricks, and wizards will perform magic...
