“This was posted after the author cleaned the house which consisted entirely of her own mess,” says our anonymous submitter in the U.K.

Of course, when you live with multiple roommates, it’s always somebody else’s mess. (Or should I say…I’ts?)

Writes Jarrod in Australia: “This was published in the local newspaper where my sister is a reporter. On first observation, it doesn’t seem like much of a passive-aggressive note, but the backstory behind it is that the owner of the paper has been refusing to have the building sprayed for spiders, thinking it unnecessary.” The staff’s response?

“For the record,” Jarrod adds, “the redback spider is related to the black widow, but more toxic (has killed people, but not recently).”

“Personally, I think all places should post this sign,” says Molly in Los Angeles.

These days, it appears a lot of cash register-operators agree with Molly (and the fancy shop in Studio City where she buys her cheese).

To wit: exhibit a, from Betsey in Sumter, S.C.

Exhibit b) spotted by Otto at a sandwich shop in Frisco, Colorado

And so on and so forth.

But I’d like to draw your attention to this piece,  spotted by Jenna at a Pathmark pharmacy in Bayshore, New York, as a true masterpiece of the genre. With just a few carefully crafted words, it transforms this common sentiment into the ultimate in shame-inducing passive-aggression.

Is it executive exceptionalism at work here? Supreme lack of self-awareness? A wicked sense of humor? You decide.

“Due to budget issues,” writes our submitter from Nashville, “coffee in our office is now funded through donations by those who drink it.” (Cost: 50 cents per cup, on the honor system.)

While some office workers no doubt continue to fill their cups without paying, the passive-aggressives in this office found their own way to convey their distaste for the new policy.

Which of these urinal notices do you find most troubling?

This one, from a London nightclub?

This one, from a construction site in New York City?

This one, from a campground in Russellville, Arkansas?

Or this one, from an office in Redmond, Washington?

P.S. “Sausage dump” wasn’t a euphemism.

“When I first moved to Chicago,” says Mike, “my grandfather told me about parking in the winter. One would dig out a spot and insert a chair, reserving the spot for your trouble.” One of his neighbors, it seems, didn’t get the benefit of such grandfatherly wisdom.

Neither, apparently, did Chris…who made the mistake of parking in an empty space outside his friend’s house in Chicago for few hours. When he got home, he found this note affixed to his mirror with glue.

And of course, Chicago isn’t the only city that takes its snow-shoveling etiquette seriously.

Just ask Anna in New Jersey…

Or Brooke in Indianapolis…

Or Amy in Washington, D.C…

Or Larry in Silver Spring, Maryland…

Or Kristin in Pittsburgh…

Olivia in Albany…

Or Chris in Boston…where they’re always keepin’ it classy.
