>E.g. a customer asks - can you make the button so you have to click it multiple times before it reacts? The less experienced (or more cynical) developer say sure, I'm on it. The more experienced developer (annoyingly) ask "what do you really want to achieve"?

That might be an appropriate response to someone in your own company. But when it's a stranger asking a specific question in a forum where such questions are asked, I give them the benefit of the doubt that they have good reasons for asking their question. If I can't answer it, I simply ignore it.
