"It's insane to think about like one company, like having such a big name brand. Like there's so many people here today and they're all here because of in and out and their, their food's so good. Their customer service is great. And they, they stay to the roots of like how good their burgers are. They, they don't outreach because they want to keep their burgers so pure. I know that much, they want to keep their farms like very local. So all the food's good. And I appreciate that because like it shows they care more about their, the consumption of the people eating than like, just like getting more money."
