Name the number of times you've heard in a restaurant, at a bar, or at a vending machine the words, "I'll have Ginger Ale" or "Get me a Ginger Ale"

NO ONE ever orders Ginger Ale (at least in my experience) in the above scenarios. Yet last week while on a PLANE to Chicago, I heard the beverage ordered at least 7 times. And you figure that's just within an earshot... maybe 1 row up, 1 row back. What is it about Ginger Ale that makes it popular on a PLANE, yet nearly extinct among other beverages in the wild? Weird!
