The company you work for is in the business of the industrial production of toilets. It just so happens that your house needs a new one, especially with christmas just around the corner. You have a gaggle of friends, family and in-laws expected over the next few weeks and all that turkey has to go somewhere.
The company typically produces luxury toilets, and the revolutionary molding process is cheap, so it's a good job you have the run of the factory at this late hour. If they discovered you using the tech for your own mundane needs, you'd be fired like a shot. Thankfully the factory produced in such high quantities that nobody would ever question one more toilet among the production totals.
Through the interface, you select from the list of models, finding the one you know your wife will love. The conveyors hum into life as they prepare to transfer raw material from the reservoirs into the molding chamber.
Aware that transporting such a cumbersome thing out of the factory without anybody noticing would be impossible, you input the command to have the finished product labelled and shipped straight to your house. The company's own postage and packaging services will help you commit almost-daylight robbery.
--error-- material reservoir #4 empty -- please refill material reservoir #4 cartridge with compound--
You grit your teeth at the interface. Bloody printers. You know for a fact reservoir 4 isn't empty, you just replaced that cartridge yesterday! You try to dismiss the error but it keeps flashing the same message. No doubt there's a loose connection in the cartridge - somebody will need to remove and replace the thing for it to correct itself.
Sleepy and with coffee mug in hand, you head off to the molding apparatus. It is a huge device the size of a small house, with conveyors and thick tubes leading in and out of it. The reservoirs are stored just inside the main conveyor, onto which they squirt the necessary raw materials, which are carried further into the machine to be converted. Normally the machine would be completely shut down before a technician enters inside, but you figure you're perfectly safe - there's nobody in the control room to activate anything, so the machine should be in standby.
Climbing onto the conveyor, you duck into the body of the machine. The five cartridges are set into the ceiling above you, green LEDs glowing on four of them, a crimson LED glowing on cartridge #4. You release the catches from cartridge #4 and wiggle the heavy thing from out of the housing.
You examine the connector on the back of the cartridge, blowing a bit of encrusted schmuts off've the metal pins. Content that that was all the error was, you wedge the cartridge back into the slot, securing the catches.
-- Cartridge 4 detected, compound reservoir at 86%, commencing molding process, depositing molding material--
Stood on the conveyor with your head tilted up at the cartridge above you, a blast of grey goo sprays out of the cartridge right into your eyes. You yell out, suddenly blinded, as you feel the conveyor lurch under your feet. Desperately, you try to jump towards where you think the open mouth of the machine is, but in your blinded state your head strikes against the hard metal interior, sending you reeling. You collapse onto your back, scraping molten porcelain goop out of your eyes, as the conveyor caries you smoothly and swiftly deep into the bowels of the machine...
