I actually do have that. I've gotten my work to make some red signs that we can place on our desks whenever we need to not be interrupted. The concept is really great in theory, but the coworkers it was meant to target don't seem to care... Just like large headphones and not looking up when they approach doesn't.
I don't think that I would use it for making coffee though.
My worst for coffee has to be dumping the beans in, flicking the switch, and then watching all the grounds just dump straight on the counter cause I didn't put the basket back...
Yeah you'd think so, at least I did too. But noooo the good people at moccamaster decided to have a small reservoir, with water from the last brew, that'll drain out through the tube in the middle when you turn it upside down. That exact thing you're hoping to accidentally discover at shit-o-clock... I was not a happy camper that night.
