I've seen bigger at a truck stop, the guy pushed two chairs together and was still overflowing. The place had these 2 pound burgers if you can eat it in so much time it's free deals. He ordered two of them,  the waitress responds with "you know that's 4 pounds of meat not counting the fixin's, are you sure you want that?" then I heard him say "never mind how much food that is get me what I ordered" I wish I knew about fph then, just the sight of him grossed me out enough to get up and leave. I wasnt about the be there and have him within my eyeshot and try eating my own food.
