Requests for available meeting times. I figure if I drag my feet on scheduling a meeting someone urgently wants to have they'll eventually just email the fucking questions and save us both 90 minutes of pointless bullshit.

I actually made an online meeting request process with a minimum 2-week turnaround just to make scheduling meetings with my department annoying. I only have so much time, and if I honored all requests I'd be spending 60+ hours a week in meetings and none actually doing my job.
