It doesn’t “bother” me as such. But I do kind of wonder why they’d speak to someone who’s proven over and over again that they can be really horrible to other users. Just because they’re being nice to you today doesn’t mean they’re not going to be awful to you tomorrow when they’re drunk, or when you say something they don’t agree with, or because they think being a twat on the internet is cool or something. And people answering their questions only makes them feel that their hissy fits are legitimised somehow. They don’t bother me, I can easily ignore them, but the people who answer their questions do go down in my estimation a bit.
