Its why I hate the show.  This would never happen because the dude would know his parents are the biggest shitlords the world has ever seen and not just ambush them.  In the extremely tiny chance he did try to ambush them in public in order to prevent a scene he sure as hell would have left after the second comment about her weight.    One of the clips I saw on the show it was some little girl bitching and insulting her dad for not getting her shoes.  I mean first of all what kind of dick dad would take his daughter to a store selling the object she wants if he does not have money.  He the dick not her for throwing a fit and calling him a loser.  But, when no one bite on this family situation that is no one else business they had the girl go up to each customer to tell them how much a loser her dad was.
