Every time McDonald's raises their prices, they decrease the size of the burgers and fries. (yes, the count the number of fries you get) They all do this, but McDonald's is the worst. Granted, I am a large guy, not fat, but big, and I could eat a so called "Big Mac" on a toothpick. It would several of them to make meal for me.
If any of us went back in time to the 80s, we would be astounded at how large the burgers were. A double whopper in the 80s was g*ddam meal. It was delicious and huge. They are still good today, but with all the regulations on fat, and lard, and sugar, etc., the taste only similar to what it once was.
But yeah, for me, the portions have become ridiculous and not worth the price. Instead of paying $10 for a burger meal, I can go to an all you can eat buffet for the same price and eat until I pop.
