The worst is when you do write up docs, there are links to the docs, but then people ask questions answered in the docs, and then fail to even really attempt to read the docs after you tell them it's in the docs.
Often people want a quick fix designed specifically for them, and do not want to read even a few pages of docs.
Yeah there's definitely a lot of entitlement from people in open source/volunteer projects. I will just say that as programmers we're far better equipped to handle the frustration of errors and have the patience to solve problems on our own. These things do often get out of hand though as I've seen in many GitHub issues.
