I'm not watching it, just because this particular case does will do my head in, but as you say in your original post, this is an exceptional case.
Your average person relying on benefits doesn't have 50 kids (or however many she's got), nor do they have the latest tv's/phones/mod cons.
At a time when there are more and more people relying on food banks, and making that choice of 'heating or eating', stuff like this annoys me. It's stigmatising people on benefits, and that's no right.
