As I said - don't blame the spectators. That was pretty much your fault in how you presented the trick. Not old people man, your presentation. If you want reactions, you have to work for them. You can't just expect to present the same thing without any work to everything and for them to simply react. And as someone said earlier, no reactions doesn't necessarily mean anything. Judging success by reactions is a fallacy.
But your attitude towards a heckler (?) is alarming.
Sorry man, but no sympathy, blaming others won't help you in the future, but it says a bit about the magician you are, and if I'm right you'll probably ignore everything that could be helpful in this thread, including this post.
