My experience and my local pizza joint I walk in and sit at the bar and there is this 20-year old fatass at the bar, wolfing down an extra large pizza all by himself.  He is already huge for his age.  I ask him "Is it good?"  Little does he know, I have no intention of striking up a serious conversation with this guy who looks like he would be a drag and dead in 5 years anyway.  His eyes light up like I just handed him the Holy Grail, brimming with melted Cheetos.  Then he goes on and on about what I should buy, saying that he usually gets the large nachos and eats it two handed.  He is nice enough and I hide my secret disgust.   The look on his face was like an addict.  And the sound of his voice was just...odd and unsettling.  He is a food addict.  That is it really.  I just don't think fatties hear themselves and they surround themselves with like-minded people who think that this attitude about food is healthy and normal.  It is really incredibly sad.
