The other day
my boss turned on the old industrial dishwasher in the cafe, having filled it up with plates.

Trouble was, he'd forgotten to shut the door first. A series of jets of water burst from the machine's stomach, picking up pieces of cheese and potato as they escaped, gleefully splashing him from head to foot. When he eventually manages to get the door shut, he decides that it would be a good idea to mop the floor early that day. Hm.

That dishwasher gives us a fair amount of fun anyway. It only has one button that works, and the other buttons (to the best of my knowledge) serve to find any weakness in the ancient door and spray water through it at random intervals. This makes training confident new people quite fun, as they always try to skip the introduction talks, "I know how a dishwasher works!"

Finally, if we put plastic beakers in it they fly around and make clonking noises, but don't actually get any cleaner. But for some reason, despite being powerful enough to do that, the dishwasher appears to be vegetarian and refuses to clean any pate from any plates.

Another good one is...
... forgetting to change them from "Pans" to "Glasses" when you bung a tray of glasses through.

You get a nice sandblasting effect on everything you put through for a few washes after though.

See, this one doesn't even have any settings
You pretty much shove anything in and press "go".
