Job Centre Dread

That familiar pointless job centre dread. Why do these places inculcate in me such a sense of despair? I have an interview there this afternoon. It's not for the money (I left my job voluntarily so as far as I know I won't get any money) but to make my housing benefit application easier. Despite this, an air of anxiety hangs over the whole thing, as if I might give the wrong answers and get myself into some unspecified form of trouble.
