In-n-out is privately owned, and puts out a solid, consistent product at a reasonable price. The menu is simple, and the facilities are always adequately staffed (even though they still get crowded). I'd heard that the wages and benefits are well above par for retail fast food. It's basically what you get if you're in the fast food business for normal reasons (and maybe a mild amount of greed) instead of unlimited greed like every other business and industry.
Biggest flaw? The owners are christian and put a bible verse on the bottom of every soda cup (not even the verse itself, just the name of the verse).
In-n-out and Costco are at the back of the post revolutionary tribunal line for me; hopefully they just voluntarily nationalize after and make it easier for everyone. We will have our hands full with Amazon and the US defense industry anyway.
