Scene: Grocery store checkout line.
IDIOT walks to checkout aisle and puts a bag of gummy bears on the belt. IDIOT looks at sign above him that reads "Candy-Free Aisle." IDIOT holds up bag of gummy bears and looks at CHECKER.
Idiot: "Does this mean I can't buy these here?"
Idiot: "So, what you're telling me is I can't buy candy in this aisle?"
Idiot frowns and points to "Candy-Free Aisle" sign.
Idiot: "So what does that sign mean?"
Checker: "I don't know."
Idiot snatches his gummy bears from the checkout belt and storms to another checkout aisle.
I'd wear a button that says, "Idiot-Free Zone," but idiots wouldn't know what it means.
