When you mix two of the listed items (Alcohol, Tobacco, Firearms, Explosive) together, the BATFE HAS to step in to ban it. It's the law. You can look it up. Honest it is.
How's that saying go? I want to live in a country where there exists a drive up for fast food, a drive up liquor store, and a drive up gun store; and where you can use all three on the way home.
