* Leave full (or partially full) carafe under spout while brewing.
(A reasonable mistake in this case, since there are two machines next to each other, but it makes just as big a mess on the floor. And no, it wasn't me.)
Ummm, that would be me...
I did that with a basic old Mr. Coffee machine, at an office, leaving some coffee in the pot when I set up a new pot to brew.
In my defense -
It was one of my very first temp office jobs.
I was all of 18 years old.
I had never brewed coffee in my life.
Neither me nor my parents had ever owned a coffee maker like that.
I still remember grabbing massive amounts of paper towels and stopping th emess before it got down into the drawers in the file cabinet it was sitting on....
Luckily, everyone was very nice, probably because few people can yell at a girl who's 18 (and looked about 14) and is obviously about ready to cry.
