That's the secret compartment in the back of my family truckster. I was always looking for change in my car. I could never find change. I hate carrying change.
So it finally dawned on me that I should take those two huge canisters full of coins that I had at my house (which had accumulated over many years) and simply dump it in the back. Success! No more looking for change.
But I know one of these days a huge question mark is going to form over some DPS Trooper's head.
