I used to work in a shared space that was once a dance studio - high ceiling, polished timber boards, etc. A freelance copywriter who was in the mix used to have a cheap white gazebo around/over his desk space.
It was novel but tacky so I set to cutting a couple of gazebo threads each day with a scalpel to hasten its demise. He never noticed and ended up moving out before the thing collapsed.
It was a $20 tent, much despised by others in the office. The person in question thought it was hilarious when I later told him about the scalpel treatment and stays in touch 5+ years on even though he's 20 years older and works in a different field. He was just that sort of larrikin who appreciated that sometimes a scheme trumps an easily replaceable product. We frequently collaborated on other mischief around the office.
