Its all about litigation, you and me and every one else that lives in the real world knows that if you have muddy boots and slip off the wet muddy tracks you aint got no one else to blame but yourself, but there are those that have crept up from some other planet who do not see it this way, and they will sit on the floor gazing up at muddy tracks and thinks..oh dear if there was a grab rail there i would of been ok .. and off they goes to sue the company because they did not place a grab rail there, and so there is now a whole industry devoted to seeing into what might and could happen so company dont get sued. Happens more in the States than over here, but its getting like this here now.
But as for nanny state ..well what does one expect with a socialist goverment, like the useless one here in the UK, all they want to do is regulate you.
