Though, it's just that, one of the things that Caroline actually, er working on with Warwick University is a way of re-looking at public services and how there funded right, it's basically to help David  to make the case with Margaret Margaret  for more money with the local Government, but erm I mean the sort of things we've been getting into is like when you considering paying for public services, should you, should you pay like in advance like through the National Insurance System or like, like I mean the French Health Service for example, people pay it for ambulances when they use them, though they pay on a differential rate, but I mean it's an issue to debate, it's right, and I've just been thinking about lavatory while you've been speaking.
