They're 'a bit like that' over in Q&P.
Not much sense of humour or patience.
though there's a guy called Lie-In King (clever name) who is not patronising....
I find myself getting annoyed when someone else replies with almost the same answer as yourself sometime after you posted it. Happened to me last night and i'm often tempted to write "hello???? can you not see my reply then?" to the other person. And yes, I know it's petty, but it still rankles.
I must admit, if people post a question without obviously having looked a few pages at least back to see if it's already been answered, it can be annoying.
