So I'm a dishwasher...

...and tonight something odd happened at work. I loaded up a dish rack with plates and bowls, and on the side of the rack furthest from me I put a tray, them shoved it into the dish machine. When it came out the other side, the rack had been turned completely around, as if someone had picked it up and turned it around. The tray was on my side now. It's not possible for anyone to have touched it because I was right there the whole time and no one came back there. I didn't have much time to think about it because I was in the middle of a busy shift, but now I'm home in bed and it's all I can think about.
