I always spill coffee. I don’t know how I manage to do it quite as often as I do. I’m not a sloppy eater, but I do tend to either slosh my coffee over the rim of the cup, or somehow miss my mouth when trying to take a sip.
I also had a bad experience with Snapple once. I have a habit of shaking them even while I’m drinking a bottle (closed, of course), but it wasn’t closed when I thought it was and ended up emptying half of the contents of the bottle. In my face. And down my top.
