So you're in line at the grocery store. The kick-off to the big game is just minutes away. You plunk your three six-packs down for payment. And the cashier's face creases.
Sorry, he or she tells you, under state law, you can only buy two six-packs at a time. If you want that third one, you're going to have to buy two, bring them out to your car, and then come back inside to buy the third one.
Or, say for instance, there's a spirit or wine that you happen to love, and, by happenstance, it's not available in Pennsylvania. Under state law, you can't have it shipped to you.
