Re: "on-premise" !?
"WTF is "on premise"?"
It means on one, a single, property. Premises, a plural, should properly point to multiple properties. Language changes over time, and the use of the singular is an evolution of the term, which originally refers to the collective of the land and the buildings, but the logic falls apart for a empty tract of land (thus nothing BUT the land, a singular; you wouldn't use a plural noun for an individual thing now, would you?). The term "on premise" (meaning on the same property on which it was sold) has been written into state laws concerning alcohol consumption for some time now, so it has legal precedent attached.
