I was told to build a logging app for one of the work streams on my project. The lead briefly brainstormed about the data fields they'd need to log and told me to go make it.

I am handing off the app and they ask me what they are supposed to put in each field.

Me: oh [team lead] just told me to put in these fields, but you guys are going to use it so why don't you tell me which fields you need and I can change it easily.

They refuse to tell me how to build the app they're going to use and will definitely complain about it not doing what they want later.
