If all of that was about her having inexpensive access to “comfort food” then I wouldn’t want to be around when she’s uncomfortable.
She is surprisingly thin. I used to like all-you-can-eat buffets when I was young and ate like a pig, but the older I got, the more I got disgusted at the gluttony I would see in those places. Heck, in regular (cheap) restaurants, the portions are too big, usually overflowing with crap you don’t want in your body anyway, so the idea of deliberately cramming as much cheap, greasy, processed food as you can and seeing that as a “win” is repulsive.
