New Hampshire liquor stores are all stater run, but beer and whine is sold in grocery stores. Gas has been self-serve for many years. I remember reading about one state where self service was allowed, and some folks didn't know how to deal with it. Oregon, maybe? I do remember intending to pump my gad in NJ, and an attendant telling me it wasn't allowed.

Seems like most everywhere is trying to avoid paying people to do a job. It's all about who can make $.
