It's untrue that Michigan is the only place where it's called "pop." See www.popvssoda.com for statistics; briefly, it's called "pop" across most of the northern US from Buffalo to Portland, "soda" in the Northeast, Southwest, and around St Louis, and "coke" in the south. It's always seemed kind of silly that they call it a "party store" instead of what it is, liquor store. I remember that Meijer used to call it the "Party Pantry" which seemed even more nondescriptive. I suppose that if hard drugs were legalized they would come up with some nicer phrase for "crack store." IGA stands for I Get Annoyed.
