I was in Argos once, and this couple of chavs were sat waiting for their order. Their toddler was in a pushchair, and she dropped her crisps, so the mum got up, called the little girl a "fackin MONG" and slapped her round the face. Then the dad got up and set fire to her hair, before unbuckling her from the pushchair and hurling her into a stack of new catalogues.
Nobody batted an eyelid.
well it was argos, surely not as middle class as pizza hut, so what do you expect
