Honestly that makes me wonder why he won't eat at the Heart Attack Grill while he's in Vegas, since some of his recipes have more calories, fat and salt than the Quadruple Bypass Burger.
Somebody else on the last page mentioned that he wont do it because he's reliant on pushing the "Im dieting, and YES DAD, I *AM* WINNING" angle, but I also think its more that the Heart Attack Grill is kind of a place that brags about hedonism.
Yeah fat people get in and eat free, but not only would it require him to admit he's 350 lbs, or 300 or whatever the cutoff was (and to be honest considering his height I do kind of believe he's only 200-whatever, maybe hes lying about 30 pounds or something) but more importantly, the place's bigger draw is being like Hooter's basically. Technically youre right, the menu even if you took away the size aspect, is exactly up his alley, its like Hooters, its "The Man Show" food--wings, jalapeno poppers, beer, cigarettes, greasy burgers and fries, lots of cheese, and not a vegetable in the place. He would love it for the food alone even if he'd ignore the kinda sexualized shit I remember them having. I remember reading that one thing they do is if you cant finish your burger, they get some girl with bit tits in a sexy nurse outfit to come paddle you or some shit. I dont know if they actually do, or do it anymore, or if its something you can request them to do or not do; seems like thats something that costs extra.
I imagine the clientele is more on average drunk people and their friends "ironically" going in there as a gag because its a tourist trap type of place, and greasy burgers are common "after the bars" food, but I kind of doubt its gonna be you going in and seeing a bunch of deathfats in a food coma.
Besides Tammy being with him (I kind of imagine her being more the type to want to hit up cocktail bars and shows and hang out in places like that when she travels rather than hang out in supersized boomer tier strip mall Chillis type places), I think their kind of low-key shaming does work on most of the people who would fit the "free food criteria". People like Amberlynn, or Jack as you can see by his treatment of his health crises, also can sometimes tend to be people like "Well Im bigger, but Im not 600 lbs/wheelchair bound, so Im not THAT bad". Plus the quality of their food actually looks pretty shit and while Jack would be okay with it I imagine some people would be like, "Vegas has world class restaurants, I could get some ridiculous oversized pub burger anywhere, even at some shitty dive in an 8,000 person small town. If Im paying for Vegas I wanna try shark fin soup or some exotic hipster foodie shit you cant get anywhere else, not shit thats not just Americana, but shitty Americana."
