Looks like someone I work with discovered one of the reasons I open the coffee packages with scissors rather than by using the brute force method. (The other is because I hate being defeated by laughing plastic that pretends to have a split that I just can't start a tear at.)
I just went down to the kitchen to get some coffee, and discovered that (1) the coffee carafe was nearly empty, and (2) there were (dry) coffee grounds all over the floor.
I went into the drawer to grab a new bag, and saw that there were grounds all over that drawer too. So I emptied it of the full bags. Then the clever drawer defeated my attempts to (without crawling around on the floor for too long) remove it from the sliders so I could dump the grounds into the trash. *sigh* So I scooped out the grounds I could and then removed the tailings with a damp paper towel.
And of course it will probably be assumed that I made the mess, since someone observed me cleaning it up.
No, I didn't clean the floor as well. That I can more easily ignore. (Of course, if it's still there in the morning, I'll probably borrow the vacuum.)
