I worked at two McDonald's off and on while in high school and university, for about a total of three years combined, and I have to say that, unfortunately, I still love the way their burgers taste better than any other restaurant chain. It's something I've enjoyed every since I can remember, and that's probably a large influence.

However, I will agree that while I still like their fries, I much prefer the fries sold at Burger King and other various "local" chains, like Steak 'n Shake, etc...
