Cynthia in San Francisco says she was about to check the class schedule at her gym when she saw that their website was no longer operational. “There is so much YES going on here,” she says, of the screenshots she was able to grab. “I barely make it to the gym anyway and this is a great excuse to quit altogether. I’m more of a yoga person anyhow!”

I’ll start with the moral of the story first: “It just goes to show you that passive aggressive notes are funny but not effective.” That observation comes courtesy of Janell in San Francisco, who admits that she penned the following note after her third coffee mug went missing from the office kitchen.

Explains Janell: “While a lot of people commented on the note, my mug never appeared. After six months passed, my boss bought me an identical mug just so I would take the note down. A year later, one of my co-workers quit. We found the mug in his office.”

Fun fact: according to a Pew Research report, 30% of young adults have pretended to be using their phone in order to avoid interacting with the people around them.

If you’re one of them, here’s a head’s up: Your awkward penguin moves aren’t gonna help you at Gestalt Haus in San Francisco.

Adds our submitter, Carly: “Even though I bought plenty of beer while I was there, I still felt like I needed to make eye contact with the bartender when coming out of the pisser. And that gets a little awkward after a while.”

Kristen in San Francisco says the copy room is ground zero for office arguments, such as this battle of the “enviro people.”

Meanwhile, Ryan in Minneapolis says his building manager left the following note on the mailbox, apparently “after a vagrant left a little ‘present’ in the recycling bin.” Adds Ryan: “Why he thought anyone in the apartment house would do such a thing is beyond any of us.”

Bob from San Francisco’s explanation: “Partied till 5 am, slept in and missed work, found this note under my door, had to take the walk of shame to find the hose and wash the sidewalk down.” Pooooor Bob, right?

Meanwhile, in Kentucky…

Writes Kris from Texas: “As much as I despise the writing-a-note-from-the-POV-of-an-inanimate-object technique so familiar from my years in college, I have to feel this bike owner’s pain. I also really love the blood-gushing-from-the bike drawing.”

I’d nominate all three of these for inclusion in the encyclopedia entry for “petty office debates.”

One reason that notes of the do this/move this/clean this variety inspire so much ire among recipients is the fact that, more often than not, writing the note probably took more time and effort than it would have for the writer to just do/move/clean it themselves. (But of course, to the martyrs in the office, it’s always about the principle of the thing.) Office kitchens seem to be ground zero for this particular type of pettiness.

At Jacqueline’s workplace in San Francisco, for example, “someone left a clean mug on an empty counter” — an offense that was apparently too grave for one coworker to let slide without comment.

Meanwhile, in Ohio, our anonymous submitter came into work one morning to see this note “on a table with maybe two crumbs on it.” Her solution? “I took the picture, put the cleaning supplies away, and moved the note. Later, I was thanked for cleaning the table.”
