Hey, I remember GOING to one of the first opened locations and getting a 15 cent burger! Yep. When my kids were little, small fries were 25 cent.
Of course, when I was in high school, gas was in the 25-29 cent per gal range and we had to all chip in our change to buy gas to cruise around. It's all relative, $100 was a BIG house payment...won't even cover electric now.
