After attempting to restart the coffee machine, it still won't work? Don't worry, you're not alone. Follow these steps to save humanity from certain doom (or at least, certain dehydration).
Step 2: Bleach The Machine
Bleaching the coffee machine involves spraying its internal components with high-pressured bleach water jet. This will dislodge any clogged up coffee grounds and restore the machine's former glory.
Warning: Be careful not to bleach your hands, clothes, and eyes in the process. We can't have our top engineers out of commission during the apocalypse.
