It's not so much bad coffee, but I thought my teenage son was going to laugh his a$$ off at me that morning. I grind my own beans in a Capresso burr grinder. The thing is white with a clear bowl with lid on top for holding the beans. One morning, in a sleep induced haze, I pulled out the grinder, grabbed the jar of beans, and poured a heaping scoop of coffee beans into the grinder. Problem? Forgot to take off the domed lid. Coffee beans rained down the side of the grinder and all over the counter top, floor, everywhere. We're still finding them a month later.
