Some of them purchase ingredients from those companies, and then make the food using those ingredients.
A great deal of restaurants, though, simply purchase pre-made frozen foods from those distributors, re-heat, and sell it to you at a premium without disclosing while you think it was freshly made. Mac & cheese, stuffed peppers, lasagna, burritos, most 'bar snacks' you can think of, etc.
I single out articles because I know many people consume AI video slop when they are tired and just want to disengage, like eating junk food.
basically any food establishment that has "supply chain operation" is slop to me; I guess it's similar to my distaste in reading AI slop too
I don't fault ppl for going (and enjoying) those too- Chili's can be enjoyable after a few beers
happened to me once lol, will never forget that place ever again (blech)
