Ok. That's quite a situation you've got there. First of all, I've only been doing magic for about a year and some change. I do my best to learn three good pieces of magic and master them. I take it one at a time. My first routine was ACR I've done it probably a hundred times and I'm just now getting comfortable with it. Some people would say I take way too long, but I like to be in complete control over my audience and the situation.
Secondly, (call me selfish if you like) I never tell anyone where I buy my magic supplies. (I'm not saying that you did...) If they want to know bad enough, they'll find it. I guess I'm trying to say I'd never be in that situation where I'm teaching some guy magic that goes right out and exposes everything I've taught him. He may not mean to, but I just wouldn't do that.
Lastly, sounds me like the guy you taught isn't that willing enough to put the time, effort, and practice into a trick to make it baffling, amazing, and genuinely entertaining.
Just not my style.
