Imagine somebody shopping for shoes in a store and finding a nice pair, and instead of trying them on or looking at the size themselves they ask other customers what size the shoes they have picked are, and whether they could put them on for them. Why? Are they illiterate or disabled and need help doing that? No, of course not - they just don't want to go through the effort of doing it themselves, silly.
Upon being told that that's kind of rude and they can easily look up the size and even put on the shoes on themselves they act indignant and tell you to mind your own business. After all, they weren't asking for advice - they were asking others to do their work for them.
Do you think that this is acceptable behaviour? Because as far as I can tell one of those people in the above example is acting kind of entitled.
