Where do McDonalds get away with claiming their burgers aren't smaller?
I did some school math project using McDonalds in the day to work out mass, as Quarter Pounder was 12cm in diameter back then, it's like 7cm now and way less mass. It used to use patties more closer in size to quarter pounder patties.
Even at 17-18, it would take me a while to eat a big mac and I would have to force it down by the end, now it's like the size of what a small cheese burger.
