You've been deep into your work when you happen to notice the time. Oh man, you didn't mean to be working this late! Where did the time go? You need to put dinner on/ walk the dog/ pick up the kids.
You're in the middle of something, but you have no choice. You'll have to pick up where you left off later. The problem? Your work stuff is spread out all over the dining room table.
You have a few options. You can choose to put your stuff away now, and be late for whatever you need to do. You can choose to put your stuff away later, when it's time to sit down for dinner, risk shuffling things around and disrupt the flow of your evening. Or you can choose to leave stuff out and forgo dinner at the table.
