I make a presentation to explain to the boss why we had to tweak around the requirements in order to keep backwards compatibility and stuff. I take 15 minutes explaining how our system currently works and how these requirements would change it, etc etc.

"So... is this workflow okay for our customers?"

They stared into the presentation slide for a good minute.

"I think we should align this row over here with that square over there."

"Oh don't worry this is a demo. But do you think our customers will still be okay with these changes?"

"Yeah, but these two elements are unalligned and they look pretty bad."

I'm starting to think that fancy speech can deter people from questioning or complaining to you. I'm pretty sure they don't know their own product as well as I know it.
