As an autist i would realize its a prank but not how to respond to it.
I would probably just do the job in a super serious fashion as a way to prank back. Its not the first time where people react to me in a “omg it was just a joke” because i committed to their bit to hard. But that is what i find funny.
Always commit to it, especially if the prank is getting you to find something.
You can either stay and work, or take the day walking around going to all the shops to buy a long weight, tartan paint, left handed screwdriver or spirit level bubbles.
