I have had this happen, but only once or twice (after the person had watched the trick more than once). The people who figure it out tend to be mathematicians or engineers. Interetsingly, they usually find the trick more interesting when they know the method.
But, in general, I agree. Most people do not care enough to try and remember the exact sequence, let alone spend the time needed to work out the method.
