I'm a big Amazon fan. The difference between them and Sears is the quality of management.
Like Apple, one person with great ideas and nobody to prevent their implementation (stockholders/committee based management) can do a lot for a company.
McDonalds is public, and the quality of workers is somewhat low. Chick Fil-A is private, and the difference shows.
Btw, after your BK onion ring meme, I went and ordered them with a meal two days later. Delish! First time in at least 20 years, maybe more. Then I saw them on the menu at Culvers and tried them also.
If you like onion rings, please treat yourself to the Culvers variety. These are the best I've ever had in my life. Today I even dipped them in my chili. They are much more tasty than fries - but be careful. They are HOT (temp, not spice).
And they are addictive. ;-)
