Good Lord! I had no idea the prices had gone up so much. I have not been to a MacDonald's since my poodle Gina died in 2010. She loved the plain cheeseburger, and it was $1 at the time.
I hope I don't bore you all with my "war stories" about when I was young, but I grew up in the Pittsburgh area. Our fast food "go to" was Eat-n-Park, and they had a double decker, much like a Big Mac called the Big Boy. In the late 1950's, a Big Boy cost $.50, fries were $.20 and a milk shake was $.30. For $2.00, I would get three sandwiches, a milkshake and fries (and yes, I had no problem putting away three double-deckers) The point of mentioning this is that periodically, they had a "half price" night, and I could get the above for $1.00. I recall one day after football practice, we piled into one of our buddie's station wagon and hit them on half price night. It took three people to carry out the order. One of our guys, whom we named "The Beast" and who later played for the Forty-Niners, LA Rams and Atlanta Falcons, downed 8 Big Boys! I once saw him eat a whole mincemeat pie as if it were a sandwich.
