How is it that competing dairies can both agree and disagree on the same thing? Around here, jugs of whole milk, no matter the size or dairy, come with a red cap. But, there’s no agreement for the other types of milk - 1% from Gustafson may be light blue, while 1% from Publix green, 2% from Gustafson may be purple, while Publix is light blue, and so on. (colors used here are merely examples, I am not that much of an analyst)
If they agree for one “type” of milk, why not all. If they are going to be different, isn’t it a wierd coincidence that they all chose red for whole milk?
