You can buy just about any beverage you want, whether distributed in bottles, cans, or cartons, and you never worry about the product leaking out all over the place. However, if that product is milk, it's almost guaranteed to leak if not kept absolutely upright. Why is that? Are the dairy folks really so clueless that they can't solve a problem that EVERY other beverage manufacturer has solved? Or, could it be that they intentionally produce poorly sealed containers so that the product will go bad more quickly, and they'll sell more product? That seems the most likely explanation as far as I can tell. Shame on you for shady sales methods!
