I've never thought of it as a fun term before.

We use "park" as "I will park the car" not park as in "amusement park"

Why isn’t the “pantry” called the “food store”?

[justinclift]

Does your pantry have a cashier and let you buy stuff there?

Because a food store sounds like it does.

yeah but syntactically "car park" gets used like a noun phrase, not verb phrase, which was (to your point really) what had me think "huh?" momentarily.
