This was my second week at a new job (I'm a remote developer). I asked one of my new coworkers a question and shared my screen with him. He said "well, first you need to switch to dark mode". He uses the same software I use, but prefers a different color scheme than I do.
At first I thought he was joking and laughed it off. But he was serious. He refused to help me until I switched. So I did, and got my answer. But now I don't feel like going to him again. Am I making too much of this or should I take a stand?
