Come on my dude they are closed on Sunday for a reason. I agree that they have fantastic service and it is probably a major reason for their success, but they also have a major share of Christian Nationalists that eat there because they are Christian Nationalist and anti-LGBTQ. Anyway here's a succinct wiki that outlines their anti-LGBTQ connection and Christian Nationalism:

And here's Dan Cathy's wiki page:

In June 2021, The Daily Beast reported that the National Christian Charitable Foundation (NCF), to which Cathy is reportedly a major donor, was helping to fund opposition to the Equality Act.

And just read the wiki page for them:

https://en.wikipedia.org/wiki/Chick-fil-A

S. Truett Cathy was a devout Southern Baptist; his religious beliefs had a major impact on the company.[56] The company's official statement of corporate purpose says that the business exists "To glorify God by being a faithful steward of all that is entrusted to us. To have a positive influence on all who come in contact with Chick-fil-A."[57] Cathy opposed the company becoming public for religious and personal reasons.[58]

Feel like you almost have to be willfully ignorant to not know about the connection between Chick-fil-a and Christian Nationalism in current year though. Are you just an incredibly uncurious person?
