I encourage you, like always, pause this video and see if you can work through it. We're going to assume that she's just not going to leave her desk or wherever the things are being registered. She's not going to leave the counter until someone shows up registering an SUV. We will just keep looking at people, I guess we could say, over multiple days, forever. It will work for an infinite number of years, just for the sake of this problem, until an SUV actually shows up. Try to figure this out. I'm assuming you've had a go.
