How do you handle users who refuse to share their actual workflow?

Digging into the "why" behind a request saves so much wasted dev time.

The CSV export example is spot on half the time users just want a quick workaround for a missing visual or report.

My main issue is that some users get annoyed when you ask follow up questions instead of just saying "yes" to their request.

Do you have a specific way to ask without making it feel like an interrogation?
