More than once I've been asked to demo features that are not completed. Once was by someone who told me to do this verbally. He was not formally my manager but some nepotism was happening at the company. I wasn't able to push back on most things with him, this is one of the few things I pushed back on some directly, and then just didn't do it. Also, this was all told to me verbally - I didn't really trust this person, and am sure if someone had noticed I hadn't really completed any of these things I was claiming to have finished, he would have disavowed that he had told me to do this. On the other hand, I was under a good lead once where we were getting a lot done but had two weeks where were just doing prep work. The lead said to do a UI mockup and to mention during the demo that the UI was a mockup because "they won't understand any how" but it was the only method of some to understand we were making progress. In this case I did demo the mockups, saying they were mockups, since I did trust this lead, and we were making steady progress, he just wanted demos to show something UI displayable every sprint.
