Hate to be that guy, but it is worse when they catch you at your last stop. And even worse when this happens as you'd have been rolling into the weekend, and worst of all -- vacation.
By the same token, there are few things better than seeing the green light flash a couple minutes into your drive back to the bldg. I laugh from pure joy on those occasions: "Too late!"
As another comment pointed out, it's always worth clarifying if you're being asked or instructed. Here the messages are always ambiguous -- purposefully so, I think.
