I hate when I rely on others following the rules and they screw me over by breaking them. We had "focus hours" at work. They would have been amazing if not for some special individuals that decide it's OK to waste my 15 minutes to save their 10. Now we don't have focus hours. Or we should document everything on wiki. But why do it when better "documentation" is "ask A". And A is on vacation. That's why I despise rule breakers, they almost always make someone's life worse. And that someone else follows the rules. Rules should be for everybody or nobody.

When someone tries to schedule a meeting during my focus hours, I decline it.

When someone DMs me about an issue they should post in the support channel, I link them to the support channel. If they insist, I link them to it again, and I inform my team not to respond to DMs from that person.

Do not engage with people who think their time is more important than yours; if you do, insist on wasting their time in equal amounts.
