McDonalds was a favorite, but my main favorite was Rally's (changed the name to Checker's recently). They always had good food, for a fast food place. The fries are GODLY, though.
Back in my slacker days right after high school, a friend and I would stay up late and watch obscure movies. When we went out for food (as usual) we hit the Rally's, however, we found out that we didn't check the money situation before we left. I didn't have anything on me, and he had like, 75 cents. So we pulled up to the window and asked how many fries 75 cents would get us, and we heard some laughter in the background, but they told us to pull around. Well, they gave us a big 'ol bag of fries! Granted, they were probably end-of-the-day fries, but they tasted fine and were hot, so we weren't complaining.
