I've had clients ask me a question and say, "I don't want to know how, just if it is possible?" and I suppose because I think they think it is really hard, I just tell them how to do it, it's like 2 clicks.

But then half an hour later they ask me the same question the same way and so I just say, 'Yes.' and start answering like that, yes, no, yes, no, yes, yes... and they tend to like that better.
