Sure, but when you’ve got your own cow, you’re milking it whenever you want — morning, noon, or middle of the night - no waiting, no fuss, no booking, milk on tap 24x7
If you got no cow, then you’re bone dry till the shop opens the next day, and by the time you get there there's a line of blokes queuing up, when you finally get the milk it ain't as fresh as what you thought.
