The single most frustrating thing about life in Pennsylvania is the liquor law: wine and liquor in state stores only, six-packs in bars or bottle shops, cases only at the distributor. It's insane.
What a revelation it was to live in Ohio several years ago. Beer and wine in the supermarket.
Pennsylvania's system is more convenient.
At the State Stores, there's nothing BUT wine and liquor.
Bars and beer distributors usually handle all the munchie snack-foods you need.
Supermarkets are cluttered with too many other products that get in the way.
(It just depends on how you look at it!)
