You go to the supermarket and buy 1 kilo of apples, 1 liter of milk and 100 grams of ham. Everything is decimal, but you get to the eggs and buy half a dozen or a dozen. Why do we break the 10 rule on...
It's because the one hundred year old machine that makes the egg cartons still works perfectly. When producers have tried using plastic cartons with only 10 eggs, they don't sell because there's always a huge stack of familiar cardboard dozen eggs that simply have more eggs in them. Why buy 10, when you can buy twelve.
Egg producers continue to use a hundred year old technology because no one has ever built a better, cheaper and more efficient packaging method.
