Back when I worked for the paging company my territory was about 1/3 of Georgia and 1/4 of Florida.
The McDonalds in almost any small town was great, In the city it was usually lousy.
IE: "rush fries" barely off-white, limp, potato noodles. Undercooked meat on a stale bun. And of course the watery 2oz of Coke in a cup full of ice.
No way in hell I'll eat at a BK, unless for some reason I feel the need to barf. McDonalds hasn't had good coffee for at least ten years... (used to be the best stuff)
Now those Hardee's mushroom swiss burgers...
Not to mention the "triple bypass" breakfast biskut. (ham, bacon and sausage)
