Last Saturday a suited man and woman, claiming to be from Sky, called to my father-in-law's asking if he would like some sort of free channel deal. They were VERY insistent on seeing his decoder setup, so they could tell if it was "compatible with their decoder". This was after being told he had a brand new flat-screen! The woman only appeared to take notes throughout this, and they were told in no uncertain terms to feck off. Be careful out there guys.
